I posted something similar in the past, but with the season upon us I need some advice.

My son is a freshman and this is his third season wrestling on the high school team. He has been under the care of an endocrinologist for the past 5 years. He is not undergoing hormone therapy and has finally started to grow (WOO HOO). The endocrinologist was ok with him dropping to 112, but was concerned about a drop to 103, which is being recommended by his coach. He started at about 119. He is around 5'3" tall.

I don't really care if he wrestles JV this year but I cannot let him do anything that can affect his future height. How should I handle this with the coach? I am not asking for advice about whether he should drop to 103, I would like to know how to tell the coach that he will NOT be dropping to 103.
