Great question! This depends on the size of your diapers and your bottle or other core items you’re hoping to bring along. Are you a wallet person? If so, that may take up some valuable real estate in the main pocket.
In general, you will always have your wipes pocket available for wipes, and the built-in, detachable changing pad (unless you’re no longer using one), your keys, and space for cash, cards and your phone in the front.
The main pocket can fit 1-2 diapers of any size, car/house keys, a couple of snacks OR a baby bottle and a small diaper cream or hand sanitizer. If you’ll only need 1 diaper or you aren’t using a bottle, there is space for sunscreen or bug spray, a small toy, and extra masks or a spare pair outfit change for your little one.
Remove your changing pad, and you’ll have extra space in the main pocket and in the back flap--a great spot to stash your Bou-Boo Bag or passports when traveling!
