Gotcha bballdad...I did combine two different posts there....and I misunderstood what you meant when you said "he can manage it on his own" Sorry about that.
I totally agree, it will be up to him to communicate all of this when he gets to school..and for the rest of his adult life for that matter. He has to learn to be his own advocate (if that's the right word here.)
What I was looking for when I started this thread was perhaps some advice from those who had been through this before, and some avenues they used to work around their son's allergies while playing ball in college. There have been some really good replies (yours included) and I appreciate the info on people he needs to make sure he talks with when he gets to school.
