Swimming nappies

Do they tell you the weights on the sizes? I’d go by that.

We got reusable swim nappies, much easier... bambino mio swim nappy and they're sized by weight. Just washed/rinsed them with her swimming costume. She only ever had one accident in them.

Depends on how often you're going to be going swimming. If it's going to be often, get the 2-3 and see if they're the correct size. If not swimming often, get the 3-4 and use swim pants over

Get the 3-4, I would say. Then the pack will last you longer. They are pretty tight, and in most pools you have to wear a ‘happy nappy’ over the top anyway (which is crazy tight - size up!)
