I was just telling someone last night that my 5 1/2 yo son is the only one who gets hot and sweaty after playing at Kindergarten recess...I always thought it was because he is so much more active and "sporty" than the other kids (which I think IS part of it) but I never thought about the fact that his IV could play a part in that. He always seems to be just fine, but he definitely runs hot! He plays all the sports he wants to and never has a problem though.

I don't think I would worry too much about it, unless you see something that troubles you. Kids don't seem to mind the things adults sometimes do (being hot, cold, wet, etc!)...
