... or one piece swim suits if the child isn't potty trained? I'm trying to figure it out because this year we'll probably make it to at least one pool if not the local splash pad. So what do you need? I'm assuming just a rash guard, hat, sun screen, and swim diapers? Bottoms are just for looks until they're potty trained right?

And what kind of swim diapers - the disposable kind or the clothe diaper kind or what?
