Green Sprouts babyGreen Sprouts baby Snap Reusable Swimsuit Diaper, 18 Months +, Light Pink, Piece of 1

My baby is currently wearing 12 month clothing - she does have thick thighs. She is wearing the 18 month swim diaper and it fits her perfectly. I would recommend sizing up.

This is the perfect swim diaper. And cute to boot! I definitely recommend getting a swim diaper like this rather than bag and bags of disposable diapers. It's much more economical and these work better than the disposables. They're a bit small on chunky baby thighs so I size up by 1 size.

Great product, as always from iplay. My daughter is between 12mo and 18mo shorts, 22lbs, so I went with the 18mo swim diaper. I know from experience these run a tad small. The fit is good for her and should last several months. If your child is in between sizes, size up. The elastic gathers at the thighs and waist quite a bit (for obvious reasons of preventing leaks), so be aware if your kiddo has chunkier thighs or waist. These are great quality and they’ll get much use :) Yay!

I really like that it snaps on the side from top to bottom. This makes getting it off after use super easy.

Our new swimmer used this regularly in swim class. Although she quickly outgrew the size, the padding and material was high quality and worth the price.
