Baby diapers go by weight, not age. If your baby is between two sizes, the larger size gives more room and absorbency.

Disposable or reusable swim diapers?
Disposable swim diapers need no washing and are easy to pack, which suits travel and one-off swims. Reusable ones are washed and worn again, so one set covers many swims. Reusable styles close with snaps or a drawstring.
Many families keep both. Compare them in reusable vs disposable swim diapers, and see how to wash reusable swim diapers.
How should a swim diaper fit?
A swim diaper should fit snugly at the legs and waist with no gaps, because its job is to contain solids, not to absorb. Check your child's current weight against the maker's size chart, then check the fit on your child.
Sizes differ between brands, and some charts use age instead of weight. If you are between sizes, let the leg seal decide. Read the swim diaper size and fit guide.
What do swim diapers do, and what rules apply?
A regular diaper absorbs water, gets heavy and slides down, so it does not belong in the pool. A swim diaper is a snug layer for time in the water, not protection for the car ride or a nap. Change your child away from the pool's edge and wash your hands.
Many pools ask babies and toddlers to wear one. See how swim diapers work and swim diaper rules at Canadian public pools.
Questions shoppers ask
Do swim diapers hold pee?
A swim diaper is made to contain solids in the water, not to absorb liquid like a regular diaper. Change your child out of the water and away from the pool's edge.
Can my baby wear a regular diaper in the pool?
No. A regular diaper soaks up water, gets heavy and slides down at the hips, leaving gaps. Use a swim diaper for the water, and change into a regular diaper afterwards.
What size swim diaper should I buy?
Go by your child's current weight and the size chart for that exact product, since labels differ between brands. Check that the legs and waist are snug with no visible gaps.
Are reusable swim diapers worth it?
They can be if you swim often, since you wash and reuse them across a season. Disposables suit travel and one-off swims. Many families keep both on hand.
