Wow thanks for all the responses and suggestions. Leckert also thanks for the offer

I also found a Mother Ease swim nappy that has snaps on both legs. I'll have to make a decision and get one tomorrow or summer will be over before I know it
we have this one and it's wonderful! he did a very sloppy little poo and it caught it very well lol. has a mesh liner and then snazzy outer and is very thin and light.
