Someone asked me this question yesterday. I responded--Although I would not allow them to be on the swim team or sign them up for a summer camp that would have them swimming in chlorine every day, I do allow them to go into chlorine when it comes up. These times are pretty limited all things considered. These times include other kid's birthday parties or playdates at other children's homes-or even the random vacation that might include a chlorinated pool. Do I like it?
