Note from Karen: The important thing to know about all washable, reusable swim diapers is that they are designed to contain poop. They are not thick diapers and are not designed to do much at all about pee. They are just for soil containment. This has some light padding, but don't expect a full pee-flood to be contained fully in the car seat in a swim diaper. Use a diaper when a diaper is needed. A swim diaper is not the same thing as a diaper and it not the same thing as a diaper cover. The fit is different. Proper swim diapers fit snugly. They will not allow a big air bubble to form inside them and possibly tip baby's face down as the air rides up, which is scary. The snugger shape of the swim diaper means they don't fill up with a big puddle of heavy water when you lift baby out of the water, either. A swim diaper that fits properly shouldn't be very saggy but should fit reasonably snug to the body. We do not suggest using diaper covers as swim diapers. Choose a real swim diaper for swimming.

I haven't used the swim

I haven't used the swim diapers yet. However, I have great confidence in this new-to-me product from Thirsties. I love their AIO diapers and diaper covers!

Always a solid choice

Thirsties swim diaper is like a Honda. It’s pretty well made, easy to use, and 95% of folks will probably be happy with it. Contains solids (and some liquid) easily, and has multiple adjustment snaps (sides and rise) for various sized kiddos.
