I took my 5 year old nephew to a public pool there was a kiddy pool and and an adult pool. he wanted to go in the kiddy pool but i said no. with all those little babies swimming in diapers and little 2 year old brats i know for damn sure that pool is like 60% water 40% piss it would be like swimming in freakin toilet bowl..so we went in the adult pool.dont let your kids swim in those public kiddy pools thats nasty.
