Kawaii Baby Reusable Swim Diapers One Size Adjustable, Pack of 3.

These diapers work great! Though I have to say, she hasn't pooped while wearing them in the dozen or so times we've used them. I am concerned they aren't going to last until she's 2, since they are already a bit snug on her healthy thighs. Overall, great product, and crossing my fingers they'll fit her longer than I think.
