Technically, any bag can be a diaper bag. But dedicated diaper bags tend to have distinct advantages, primarily in the number of pockets, which help with organization. Plus, they can offer other added features, like insulated pouches and stroller straps. “I keep everything organized by pocket…that way, I’m not rummaging through the bag looking for what I need,” says Nemeth who stores an extra set of clothing, burp rags, pacifiers and teethers, diaper rash cream, diapers and wipes in her diaper bag.

It depends on a few factors, although backpacks tend to get bonus points for overall convenience. Here are some things to consider when choosing between backpack and shoulder-bag styles:

• Lifestyle: Certain factors may influence your best option. For instance, if you plan to baby-wear (a.k.a. wear your baby in a sling or carrier), then “this limits your options when it comes to a crossbody option,” says Playforth. And, if you live in an urban area and plan to walk a lot, a backpack might be better since “it allows a more even weight distribution across shoulders and still leaves your arms free,” she says.
• Versatility: Do you plan to use it as more than a diaper bag down the road? If so, a convertible style might be your best bet. “I want something that doesn’t scream ‘diaper bag’ that I can use for trips in the future,” says Braden.
• Comfort: Braden is a fan of the backpack style since it applies pressure evenly to both shoulders. It gets bonus points for padding on the shoulder straps.

While a diaper bag should have enough space for diapers, wipes, toys and other essentials, certain features beyond that can offer convenience and comfort.

• Insulated pockets or pouches: These can help keep bottles of milk or formula hot or cold, or simply in one spot. “I keep a bottle with water on one side and the formula powder in the other,” says Nemeth. Even once kids are older, you can use it to stash snacks, says Flayforth.
• “Parent” pocket: Some diaper bags come with an external pocket designed for easy access for parents. Playforth has found this especially helpful, since “you're not digging through endless baby supplies to get your car keys or sunglasses,” she says.
• Stroller straps: Shoulder straps let you hang the diaper bag off the handle bar of a stroller, so you don’t have to stuff it into the already-limited space in your stroller, says Playforth.
• Laptop or tablet sleeve: While you can carry a diaper bag and separate tote, a dedicated sleeve for electronics can streamline the number of bags in tow. “I don’t like carrying lots and lots of bags, so if my diaper bag can carry all the things [I need], great,” says Braden.
• USB charging port: If you plan to be out for the day, a USB charging port will ensure that your gadgets — including your phone — won’t run out of battery.
• Removable changing pad: Some changing pads are built into the diaper bag (they roll out while attached on one end), but both Braden and I prefer a completely separate changing pad. Braden has found it especially helpful for changing diapers while traveling. “I don’t have to take the whole diaper bag; I can just take the diaper-changing portion of it,” she says.
• Style: While style is subjective, you should consider what colors you’ll be happy to carry around in public. “I like gender-neutral styles so my husband can take turns carrying the diaper bag,” says Braden. My husband is usually on diaper duty when we go out, too, so our gray, backpack-style diaper bag works for both of us.
