We found about a dozen great diaper bags, most of which come in several different colors and patterns - so don't judge only by the picture we provide! Here are the top 5 diaper bags we found, followed by in-depth reviews of about a dozen different options.

The diaper bag is one of the most important baby essentials for a prepared parent. Once you leave the house, you will need to bring a ton of supplies like diapers, baby wipes, a changing pad, snacks, baby bottles, burping cloths, pacifiers, lotions, diaper rash creams, cloth diapers, and a change of clothes. Plus don't forget your own stuff, like our wallet, phone and keys! The good news is that there are hundreds of baby diaper bags on the market designed to make your life much easier. The bad news is that some of them aren't so great, and some of them are downright ugly! Here is our full diaper bag buying guide.
Here are the Best Diaper Bags of 2019!
This top-rated bag looks almost like a large purse, and might even be mistaken as something other than a diaper bag. But don't hold your breath, that's a tall feat. This bag has a stylish thick quilted exterior with tan leather, gold hardware, and red accents, which makes it look much more expensive than it actually is. Coming in at around $55, this bag is right in the sweet spot where you will get reasonable quality and high functionality, without breaking the bank. While it doesn't convert into a backpack like some of the below models, it does have some great versatility: you can carry it as a hand-tote, use the shoulder strap, or use the included stroller straps to attach it right onto your stroller. Of course, we always suggest using caution with stroller straps, as a heavy diaper bag can cause a stroller to tip over backwards. The bag itself is big, and everything about it feels high quality and thick. The fabric is actually water resistant, and we tested it out by placing it into a shallow puddle and making sure the clothes we put inside were kept dry. They were, and we were happy to see that the diaper bag lived up to its claims. This bag has 10 different pockets, one mom pocket outside and one on the inside (for keys, phone, wallet, cash), two padded baby bottle pouches on the sides, 2 front pockets (with magnet closure) and 1 rear pocket (non-zippered), and a huge main compartment that is a bit more like a purse than a diaper bag in terms of how it's divided. The diaper changing pad is well-sized and can be separately washed in the machine. It's a big bag, but not too big so that it looks giant on a medium-sized mom, or sticks out too far when hanging on the stroller. Frankly, we think it's the perfect size. We found the zippers, seams, and buttons to be high quality, and we think this bag will last you for several years. Our most popular diaper bag on Pinterest, moms love the look of this bag! Only two minor gripes: we wish the large exterior pocket was zippered or buttoned, so inquiring minds couldn't look inside (and curious baby hands couldn't reach in!), and that the bottle pockets were more thermally insulated.

From the moment we opened the box, we fell in love with this top-rated Skip Hop diaper bag! It perfectly demonstrates the intersection between style and functionality. For moms with style, it uses a classy New York style colors and black stripe pattern, with light brown leather accents. We loved the look of this tote diaper bag style. But we were even more impressed by the functionality. This baby diaper bag gets things done. It is big, well-made, and has a ton of pockets (11 to be exact). For pockets, let's start on the outside: it has insulated side pockets that were big enough to fit even the widest baby bottles and keep stored at a nicely controlled temperature. Above those on the sides are some small pockets that were very easily accessible and perfect spot for keeping pacifiers. On the front, it has zippered pockets, which we thought were great for mom's personal stuff: car keys, a small wallet, or cell phone. The inside is vast and well-lined for durability and easy cleaning. It has a huge center space, which is perfect for diapers, wipes, changing pads (it comes with a great one!), and toys. A clever divider is put in between the outside handles and the main inside space, which provides even more storage space. These were great for more upright things that you want to slide up & out quickly like diaper cream, sunscreen, and lotion. Overall, we absolutely loved this bag, and it performed very well in our testing for durability, and we think it is very deserving of this spot on our diaper bag list! Cons? A bit pricey, usually around $75. Highly recommended! Interested? Check out the SkipHop Grand Central diaper bag here.
Do you like the SkipHop Grand Central, but think it's a bit too pricey? Then this tote diaper bag is definitely the next-best option for you. This awesome diaper bag, the SOHO Grand Central, is similarly styled with some very similar functionalities, but at about half the price. While the SkipHop has most features integrated right into the bag, this one takes a different approach and has them as separate pieces. There's a separate zippered and insulated baby bottle bag, a separate diaper clutch (for disposable or cloth diapers, of course!), changing pad, toiletries bag, and a little wallet. It has 5 different little bags for various things, it took a while to figure out what it was all about. But once we did, we loved it. Being able to take everything out separately is a different style, but we got used to it and ended up liking it. Going to the register at Starbucks? Just bring the wallet part. Going to a bench to bottle feed? Just bring the bottle pouch. It made some sense, and also made cleaning a bit easier when you can wash each part separately. Like the SkipHop it has zippered front pockets, convenient side exterior pockets for pacifiers, and is overall about the same size as the SkipHop, though the opening did stretch a bit wider overall. It includes some stroller straps, which are a nice touch, though definitely use caution with a heavy diaper bag to prevent the stroller from tipping over backwards. The quality isn't quite on par with the SkipHop, especially in terms of the inner liner, seams, and zippers, but we thought at about half the price it deserved a high spot on our best diaper bags list. Highly recommended! Interested? Check out the SOHO Grand Central diaper bag here.
This is an awesome backpack-style diaper bag that is stylish, durable, convenient, comfortable, and feature-rich. It's a medium-sized diaper bag that you can carry has a hand-tote or as a diaper bag backpack. It has a modern gender-neutral style, helped by the heather gray color, the leather accents, the asymmetrical front pocket, and its vintage style button. It's the sort of bag that both mom and dad will be willing to wear, making it one of the only unisex diaper bags on our list. And it has some great features. First, we loved the side baby bottle exterior pockets, the zippered wipe dispenser on the side, and the hidden pocket on the back (up against your back) that can hold valuables without the risk of pick-pocketing. That's great if you live in the city, or travel to urban areas where that's an issue (like on the subway!). We also liked the substantial padding against the back, to keep things comfortable for longer excursions. It also includes stroller straps on the sides, though we warn you to be careful about attaching diaper bags to strollers due to the tipping hazard. In that regard, it's definitely a good size for throwing into the stroller's bottom basket, but still big enough to hold most of your stuff. Speaking of size, the main compartment is really quite large and is divided well into a mesh pocket area, a zippered pocket, and elastic pockets for holding smaller items. We were able to fit everything necessary into the bag without any issues. It's great to have a nicely divided main compartment, to prevent things from sinking down to the bottom and remaining elusive in your desperate search for that last clean pacifier! We also want to point out that this company is very responsive to customer concerns. This is their third version of this great diaper bag, with improved stitching and reinforcements based on customer feedback (and if you have the older version with an issue, you can email them and they'll send you the newer one for free!). And the price is right too, coming in around $40. So, if you're looking for the comfort and convenience of a backpack, this is a great option! Note that we also checked out the HapTim Multifunction Large Baby Diaper Bag Backpack, which is very similar and very highly recommended. Interested?

This is an enormous and stylish black vegan leather diaper bag with every pocket, compartment, and nook and cranny you need to make for a perfect journey with your baby! In our testing, this designer baby diaper bag received the most attention from other moms - every time we used it we got comments about how nice it is and questions about where we found it. And we were not surprised given just how nice this bag is. It is designed as a large tote, coming in at about 19" wide, 13" high, and 7" deep, meaning that it has nearly a full cubic foot of space inside, which is really cavernous! And it's not just inside space that makes this diaper bag amazing, it's also the two zippered outside pockets and the five additional outside pouches that are perfect for quick access to baby wipes, bottles, pacifiers, and the included changing pad (using the large back outside pocket). There is an amazing lined pocket on the front that can be used for anything wet - like a wet bathing suit or clothing, while keeping the rest of the bag and its contents dry. It also has two insulated pockets on the inside that are perfect for keeping a bottle or snack chilled during a trip, and a ton of additional space that is perfect for holding a nursing cover, blanket, change of clothes, and more. The changing pad comes with a little travel pouch that's the right size for a diaper and wipes when you want something to quickly bring with you to the changing table. It also includes a shoulder strap that you can use to carry it across your chest, and it also includes stroller straps to help you attach it to your stroller (but be careful with that!). We loved nearly everything about this black faux leather diaper bag, and thought it was an amazing addition to this year's diaper bag buying guide. The Honest Company also makes a backpack version of this bag, called the Honest Company City Backpack Diaper Bag, for about the same price, that is worth checking out if you prefer that style. Downfalls? Well if we're being really picky, the zippers were finicky sometimes, and the tote straps were a good size for holding with your hand or forearm but not quite big enough to put on your shoulder. But those are relatively minor points that are about our subjective experience. But one big challenge with this bag is the price, coming in at around $150 or so which seems expensive for a faux leather diaper bag. If you love the styling but want to save some cash, check out the Skip Hop Chelsea Downtown Chic Diaper Bag that has a very similar look and functionality but is a little bit smaller and only about half the price.

Sold at Nordstrom and other upscale retailers, the Petunia Pickle Bottom diaper bags (and backpack diaper bags) are among the most popular, super-stylish, and high quality diaper bags available on the market. The styles are awesome and range from quilted black with gold trim, to flowers and abstract watercolors. The designs are subtle and give the bags a high-end look. And the price tends to reflect that, with this Boxy Backpack model coming in at just over $150, making it the most expensive diaper bag option on our list! Its price is almost justified by its high quality and functionality. The bag we tried, the Indigo model pictured to the right, was made right here in the USA of cotton canvas that has a durable glazed coating on it for stain and water resistance. For functionality, this bag is really large, coming in at about 0.90 cubic feet of capacity. For pockets, there are several inside (8 of them), including two with zippers, and 3 outside (two for baby bottles on the side, and one larger one on the front that holds the included diaper changing station and pad). So, there's tons of space inside, and plenty of pockets for organizing baby care products, and the top opens up nice and wide for easy access. In terms of versatility, it also has several carrying options. You can carry it like a tote using the top grab handle, or use it as an over the shoulder diaper bag, backpack diaper bag, or attach to the stroller using the included stroller straps. It looks best as a shoulder diaper bag, but when you get sore it's great to have the option to wear it as a backpack. In our testing, we found the bag to be generally high quality, stylish, versatile, functional, and really large. It stands on end on its own, which is really nice - in other words, it doesn't tend to topple over like some other diaper bags. Maybe that's why it's called the Boxy model since the bottom is pretty boxy and stable. We also liked that it came with a sleek plastic baby wipe holder or diaper tote that made trips to the changing table much easier. There's really a lot to love about this diaper bag - but is the price worth it? Well, there were some limitations to the bag we purchased for testing. First, we were surprised that there was no insulated pocket for bottles or foods, not even the bottle pockets on the sides have any insulation. Second, the fabric is available in cotton canvas, embossed stitching, and a plush chenille. We actually only tested the cotton canvas, but we made the mistake of putting it in the washing machine after a milk spill, and the bag fell apart a bit - some of the stitching came loose, and it seemed like the bag lost some of its water resistance. So that was a bummer. Finally, the backpack straps aren't padded so they're not the most comfortable straps in the world - same with the shoulder strap. So definitely some limitations that might make you reconsider whether the style and Petunia Pickle Bottom name recognition are worth the price? We'll let you decide! Interested?

This is one of the trendiest backpack diaper bags available on the market. One of our most popular Pinterest pins of all-time, moms are loving this diaper backpack's styling, features, and versatility. And it's not only available in the style we show to the right, it's also available in black, an adorably flower petal design, and jersey grey. And they all look like really stylish diaper bags; in fact, if it wasn't for their enormous size you might mistake it for a stylish little backpack. Of course, you'll probably have baby bottles sticking up out of the side pockets and pacifiers hanging from clips, so dead giveaway there too. Anyway, this is a feature rich diaper bag that doesn't just look great, it performs great as well. It has 7 pockets on the outside, including two insulated baby bottle pockets, zippered and lined top and side pockets for your keys and wallet, and convenient front pockets with flap closures. And when it arrived it was much bigger than we had assumed based on the pictures; the inside is really large and there are 10 different dividers and pockets for organizing all the stuff you'll be lugging around. It's really nice actually because the diaper bag stands on its own and the front zippered pocket opens up the entire front. But when you do so, it isn't just a big waterfall of your stuff falling forward and out onto the floor. It has a mesh liner on the lower half of the interior to keep things from falling out, and when you combine that with all the different pouches and zippered pockets, you can really do a nice job organizing things in here. There's enough space and dividers to separate diapers, wipes, extra clothing, pacifiers, extra bottles, and more. Speaking of changing diapers, it comes with a cute changing pad that folds up nicely, though it doesn't include any type of diaper/wipe holder for when you want to scurry off to the bathroom with the changing pad, a diaper and a couple wipes. Some other things that it does have, however, include stroller straps (but be careful to only use these on a stroller that is loaded with a baby who weighs enough to counteract the weight of the bag!), the use of vegan leather on the pockets and tassels (so you can look good and feel good about not harming animals to make your bag), and a carrying handle up top. We also loved the bottom, with its thick rubber feet that keep the bag stable and able to stand on its own, while also keeping the fabric material from ever touching the ground. That was pretty clever! Overall, everything worked pretty well and felt decent quality. The zippers weren't as rugged as you might expect from a bag that costs $150, and there are some reports online about seams splitting or ripping after several months of use. We haven't had that issue, but we'll update this review if we do. Also, the shoulder pads could be a bit more comfortable for when you're carrying it for longer periods of time. So overall, if you must have this style and are willing to fork over the cash to get it, this is definitely a trendy diaper bag that is not only super cute but also surprisingly functional and well-designed.

This is an excellent backpack diaper bag, and one of the all-around highest-rated diaper bags you can find in the US! And there are some great reasons for that. It's an amazing diaper bag backpack that doesn't stand out as a diaper bag: no excessive patterns or colors that make it obvious, just a simple and stylish diaper bag available in black or heathered grey. And is has features galore: it can be carried with the top handle, as a backpack, and it includes strong built-in straps so you can hang it on the back of your stroller. There are so many pockets, 14 of them in total, there is bound to be one that's the perfect size for what you need to haul around! There is a very large insulated baby bottle exterior pocket on one side, pockets for little things like your phone and pacifiers, larger things like baby lotion and a stuffed animal, and there's an awesome baby wipe dispenser on the side. You won't realize how awesome that is until you fill it up and need to quickly grab a wipe while you're out. Just reach back and pull one out. Simple, and we are starting to wonder why all diaper bags don't have this awesome feature! One thing we were really surprised by is how deceptive the main compartment is: you think it's going to be small but then you open it up and realize it's actually really big. Big enough that we could fit in: The Spectra S2 breast pump and accessories, diaper rash ointment, the changing pad (it's included), burp cloths, disposable diapers (or cloth diapers), and an extra change of clothes. And there was still room to spare. We really liked how large and versatile this backpack diaper bag was in our testing. We also thought the zippers and fabric were high quality, and the fabric seemed to do a decent job repelling water. We didn't rest it in a puddle or anything, but we noticed that splashing it with water didn't get into the bag at all. So, it should be good to go in a rainstorm. It also came with a small diaper tote that's the perfect size to fit a diaper, a small tube of cream, and a couple wipes into; the perfect size for bringing to the changing table. So, overall this is an excellent diaper bag backpack that is versatile and highly functional. Only a couple of small drawbacks. First, there have been reports of quality control issues with this bag. We didn't have any issues, but some moms report ripping near zippers, or the insulated pocket coming apart at the seams. But we want to point out that this company is very responsive to their customers, and they will replace the bag if you have any issues! So that's reassuring. Second, the backpack straps and padding aren't the most comfortable in the world, but we were happy to strap it onto our stroller after our shoulders got sore. We found it online for around $60, which we think is a good price for all this functionality. Interested? You can check out the Bag Nation Diaper Bag Backpack here.
Here is a great, simple, inexpensive diaper bag that will satisfy most parents' style, functionality, and durability needs. Coming in at only about $30, it's one of the cheapest backpack diaper bags on our list and on the entire market! We got our hands on this diaper bag in mid-2019 and put it through 3 weeks of hands-on testing. The verdict? We like it! In fact, we like it so much we put it in our top 10! The style of this bag is on-point, with its heather grey durable fabric and brown leatherette trim, and simple yet sophisticated styling. We were pretty impressed - out of the box, it appears as a pretty high quality bag which surprised us given the price point. Out other first impression was that it really had a lot of pockets and storage. Right up front it has a zippered and waterproof lined compartment that can fit anything wet or moist, like a dirty diaper, wipes, or damp wash cloth. Right behind it is a larger and versatile zippered compartment that has several pockets: a big mesh pocket, two insulated baby bottle pockets, and a thin pocket that could be good for your wallet. Then it has another even bigger zippered compartment behind that, with spots for diapers, wipes, and maybe some clothes and wash cloths. Finally, it has a huge compartment behind that (the main compartment) with 5 additional pockets inside; this is a good place to slide in the (well-sized) included changing pad. The main compartment is pretty cavernous, and we were able to fit 2 formula tins and a breast pump in there without any issues. It also has what seems like it could be used as a tablet or small laptop sleeve against the back of the main compartment, to that gives it some nice versatility for after your baby is old enough to not need you lugging this around - you can actually use it for something other than a diaper bag. On each side of the backpack diaper bag is a water bottle holder that stretches pretty large and is reasonably deep (about 6"). One of those pockets doubles as a baby wipe dispenser by virtue of a little slit in the middle (so you can pull wipes out). And there is also a small zippered wallet pocket against your back for added security (makes access a bit harder for a would-be pick-pocket). In our testing, all of the zippers and pockets were easy to use, and we didn't have any issues with zipper breakage or threads coming undone. We loved the big upper carry handle, and the stroller clips that could even snap onto stroller with very thick handles. The shoulder straps were comfortable and have a nice mesh material on the inside to help ventilation. Everything adjusted well and we thought it was comfy and durable, even though it is super lightweight. Cons? Well, it doesn't really stand well on its own unless you put something heavy and flat on the bottom of the main compartment (like some formula containers or a breast pump). It has a nice logo on the front, but it does have a pretty cheesy slogan "Happiness, not in another place but this place." We also thought the diaper wipe pocket/dispenser needed to be a bit larger to hold most modern baby wipe packages (you'll need to get a 24 or 32 pack for it). Finally, the baby bottle pockets weren't wide enough to hold some of our wide-mouth bottles. And the bag overall is a good size (about 25L), but nowhere near the capacity of some of the larger bags on this list. Overall, there's a lot to love here, with only some minor limitations. Once we get through a longer-term test, it might start to creep up on our list! Interested? You can check out the FIVEMAX Diaper Bag Backpack here.
This is one of the biggest bang-for-the-buck diaper bags on this list, with great style and functionality. Note that if you don't like the pinkish coral color, it comes in a ton of additional styles. This diaper bag is a hand-tote that converts into a comfortable diaper backpack. It's very large, though not as large as the SkipHop or SOHO, but it's definitely large and functional enough for most purposes. What we loved about it is that it's only like 35 bucks, and it has some features that make it competitive with the best bags on this list. It has side pockets, one of which has a slit in it so it can dispense baby wipes! It also has a zippered mom pocket on the outside that can fit keys and a phone, and the top zippered compartment is really quite big and well-divided into a main space for diapers, cloths, clothing, toys, etc. It also has a zippered mom pocket on the inside, and an insulated zippered baby bottle pocket on the front that can fit up to 3 bottles (mostly the modern short and wide ones, not the classic tall and narrow ones). It has a clever way of dividing its space, as you can use the front pocket for just bottles, or you can push it back into the main compartment and use it for much larger things. That will end up being a separate space at the bottom of the main compartment, and this works out well because it brings the bottom of the main compartment up much higher (which makes it less likely to lose things in the depth). Overall, we found this diaper backpack to be really excellent for the relatively low price. Don't expect super high quality hand-feel for the fabrics at this price, or expect anything fancy like stroller straps or removable zippered pockets, but we think you'll be surprised with what they've pulled off!

Skip Hop makes some excellent diaper bags, and this one is no exception. The Skip Hop Duo Signature has a slightly more modern styling than the classic lines and colors of the Grand Central models, and is shaped more like a tote or over-the-shoulder bag than it is a purse. It's narrow and deep rather than wide and short, and a bit smaller overall than the purse-shaped models, so it's good for someone who doesn't want to be lugging around a truly enormous diaper bag. It's also about the same width as most strollers, so it doesn't stick out on the sides a lot when you hang it on the handlebars. But while it's smaller overall, it's still super functional. It has 10 pockets, a separate insulated bottle holder, a breathable side pocket, a key ring clip, diaper changing pad, and a great interior liner. The Skip Hop Duo's main interior pocket is super deep and we loved the lining, it was soft but also rugged enough to make wipe-cleaning easy. The padded shoulder strap was comfortable, as were the padded carry-handles. We were able to fit everything in that we needed, including diapers, wipes, baby bottles, and cloths. Being relatively tall, we found that when it was fully loaded it did tend to topple over sometimes. We also found it less convenient to reach in and easily grab something, since things tended to get stacked on top of one another, so this design might not be for everyone. Also, the changing pad was a bit small relative to some others on this list. So, this Skip Hop Duo Signature model is an excellent diaper bag, with some minor drawbacks. Note that Skip Hop also makes a Skip Hop Duo Diaper Backpack that is very similar to this but in the backpack style, and is also very well-reviewed. Interested? You can check out this SkipHop Duo Signature diaper bag here.
This is our highest-ranking convertible diaper bag, and we love the style and functionality of this versatile and relatively unisex diaper bag system. The bag converts from a regular over-the-shoulder diaper bag, to a messenger bag, and to a super comfortable backpack with soft shoulder pads. So just when your arm or shoulder is getting sore, you can untuck the backpack straps from the side pocket, and off you go, in style and comfort. But it's not just versatile. This diaper bag is also super functional. It has outside and inside pockets, 3M baby bottle insulator pockets, and clever see-through plastic pockets inside so you can see what you're looking for before you go searching. It's relatively small, but we found it big enough for one baby, and the fact that you can open the main compartment nice and wide really helps you fit all your things in (and prevents you from randomly searching for things). But it does have a few drawbacks, given its high price (like $170). For this price, we would expect a bit higher quality on the fabrics and zippers. They're good, but not quite on par with the heavier duty zippers of a SOHO bag, or the easy-clean fabrics of a SkipHop bag. So while it's on our list of best diaper bags, and we think it's worthy of inclusion, these drawbacks will keep it a bit lower in our reviews and ratings. Interested?

Diaper Bag Buying Guide:
When choosing the perfect baby diaper bag, there are several factors you should consider. Think about how you want to carry it. We suggest lugging around a 10-pound bag with you for an hour and see whether you find yourself wanting to throw it on your back. If so, then definitely consider one of the convertible diaper bags that can convert into a diaper bag backpack, like the Ju-Ju-Be (above). If your arms and shoulder feel fine, you might be OK with a more conventional bag. This might be a tote diaper bag that uses large handles and a shoulder strap, or a messenger style diaper bag worn across your chest. Better yet, check out the convertible diaper bags that can easily swap between a tote with shoulder straps and a diaper bag backpack. You'll be thanking us when you take it to Disney! Also, think about what happens when you need to do other things, like pull your baby in and out of the car seat. Will it flop annoyingly off your shoulder, stay on like a baby diaper backpack, or can you place it on the ground and not worry about it getting ruined by some water or tipping over and spilling its contents? The water issue is why we don't consider leather diaper bags in this article, given our less than stellar experience with liquids and leather bags (water, milk, lotions). But if you really want the stylish black leather diaper bag, check out the other faux leather diaper bags, like the Honest Company bag (above), a faux leather diaper backpack, or this faux leather Skip Hop Chelsea Diaper Bag.
No matter which style you choose, you should think about how you'll be able to put it onto one of our best strollers: down in the stroller's basket, or would you like to hang it on the stroller's handlebars? If the latter, you should go ahead and buy a diaper bag that includes stroller straps, like several of our top-rated bags. We suspect you'll use that feature a lot. Of course, always use caution when hanging the diaper bag on the handlebars of your stroller: when you take your baby out, the stroller will flip over backwards (unless the bag is super light)! So definitely make sure that the stroller you choose has a nice large basket to fit your diaper bag.
To figure out how big of a baby diaper bag you'll need, put some thought into how many things you'll want to be carrying around. It's not just for baby diapers and baby essentials (dont' forget nipple cream, lotions, baby sunscreen, and maybe even one of the smaller best breast pumps), but the baby bag will also be responsible for holding the contents of your purse unless you plan on carrying both the baby bag and your purse around all day (which we don't suggest!). So that means you'll want to make sure the baby diaper bag is big enough to hold all of the baby essentials along with things like your wallet, keys, lip balm, tissues, makeup, sunglasses, and anything else you carry around in your purse on a daily basis. Otherwise it's not really about finding the right diaper bags for moms, it becomes more about shoving in all the baby stuff and leaving mom's things behind!
Also, pick a bag that will last you both in durability and style. If the bag only looks good with certain outfits, you'll find yourself frustrated or wanting to buy multiple bags. A black or red bag, or one with relatively neutral colors/patterns can work with nearly any outfit. Of course, some of the really stylish baby diaper bags can also get really expensive; so maybe dig into some of those gift cards you might have hanging around from your baby registry, or put your favorite on a new baby registry (see our best baby registries here) if you haven't had your baby yet! Finally, it's worth considering a diaper bag that is water resistant, to protect the bag's contents from damage during rain or accidentally being set on a wet surface. The Halova Diaper Bag Multifunction Waterproof Travel Backpack is a great example.
