S.M.
Both my girls had tubes. The oldest still has hers in place, and is prone to ear infections if we don't use plugs even in the shower. I forget the name, but almost every pharmacy has them...they are a red putty like plug that are sized for adults. They break apart very easily and mold into the ear. We use 1/2 plug for each ear and re-use it a few times before throwing it away. Every once in awhile, one will fall out during the shower, but it is the exception, not the rule. Swim time is a little rougher play than shower and baths, so we use a head wrap http://www.leapsandbounds.com/catalog/product.jsp?product... . It is more for keeping the plugs in place than keeping the water out. Hope this helps.
