I just signed DS (almost 1) up for a swimming class starting next month. It's at a public pool and they say babies need to wear both a swim diaper and a diaper cover plus their bathing suits. The bathing suit I'm thinking about getting for DS also has a mesh underwear lining so I'm thinking he'll need a little extra room to fit everything in there. Do you generally need to go up a size in bathing suits to accomodate the bulk of the diaper and cover? I know bathings suits can tend to sag so I'm just wondering what has worked for others. TIA!
