We are at the weird time with our son where we really don't need a diaper bag, but we still need something. It holds, a few diapers, wipes, change of clothes, snacks and a sippy cup just fine! It's small enough to put on my 1.5 year olds back, and it seems to hold up fairly well! We have the cow backpack bc I don't see it very often, like the bee or the unicorn, and it's super cute!
