Our little one (18 months) started swim lessons about a month ago, so we're learning all about swim diapers and trying to avoid an accident until we get to the pool. We've changed in the locker rooms and got in the habit of just putting the swim diaper on in the trunk upon arrival. With a wiggly kid, that's just a pain but we dealt with it.
Last week, my wife was in the water and I stayed in the chairs where I overheard two of the other moms talking and one had an awesome suggestion we hadn't thought of. Put on the swim diaper at home, then put a regular diaper on over the swim diaper and take off the regular diaper upon arrival. Keeps everything contained, makes changing a lot easier, and we're in the pool a lot faster.
Curious to see what the community has and see if we can get some knowledge sharing in! What else have you got?
