I have been using JuJuBe for years and the Be Quick has been my favorite go-to back. It can hold a couple of diapers, a small pack of wipes, and some disposable changing pads for those quick changes. For toddlers, it could easily hold a pull-up, change of clothes, and some underwear. Now that my kids are older, I use it as a small crossbody or to hold other items inside a bigger bag. Makeup, toiletries, pens, you name it! Like many of their items, it's so versatile! THIS PRINT IS AMAZING!!! the adjustable is a huge plus as well and there's a tiny zipper pocket on the inside. GREAT BAG!
