We are going to Punta Cana (woohoo!) the first week in Feb for some fun in the sun. Anyway, I want my LO to get in the pool and ocean a bit and play around. How does this work with a diaper? I've found all sorts of cute swim trunks and little rash guards to help protect from the sun but not sure if there's something else that would be better and prevent a soggy diaper.
