Paul,

 

Just to give you another perspective, my son usually does better in the summer even though he is swimming in public pools and freshwater lakes. I don't doubt that chorine could be a trigger for some people, but it just  isn't a problem for my son. 

 

My son always had drops when he lost a baby tooth - I think it was either the inflammation or mild infection. He also drops when he has a sinus infection.
