Swim Diaper 101

Watching your baby giggle as he splashes excitedly during his very first dip is the sweetest. Realizing when they announce "Everybody out! We need to shock the pool" that your budding Michael Phelps was the cause? Less sweet. The right swim diaper is key.

You'll find plenty of swim diapers to choose from, but they all have one thing in common: they're not absorbent like a regular diaper, but designed only to hold in solids. (Pee will pass through, but that's why public pools are so heavily chlorinated. It's the bacteria in poo that's the problem.)

You can choose reusable swim diapers, which can be washed, or disposables. Each have their fans among parents. Worth noting: If your baby is exclusively breastfed or hasn't yet started solids (in either case he'll have poop that is more liquid than solid), reusables tend to do a better job than disposables. Still, you'll want the backup of plastic pants over the swim diaper, as well as really snug fit around the legs.

Here are some of the best baby swim diapers you can pick up this season.

Beau & Belle Littles

Uber adjustable, Nageuret diapers have snaps that adjust around the waist and legs, and three different size adjustments for height. So infants as light as 8 pounds and toddlers as heavy as 60 pounds can rock the trendy patterns designed by Beau & Belle Littles. They're lined with a super soft mesh to be gentle on your baby's skin.

This company's business practices are impressive, too: If anything happens to one of their swim diapers, they refund your money and give you a new one. Plus, 5 percent of their sales go to Compassion International.
