L.F.
If he has silent aspiration, one of the 1st folks I'd have him see is a speech/language pathologist (SLP) if you haven't already. The SLP can give you recommendations how to avoid this. This can lead to pneumonia and hospitalizations...Also if he's small for his age maybe he's not getting enough nutrients?
My nephew is also small for his age and I believe that he saw a geneticist-and he's just gonna be small. He's very involved in gymnastics and is great at it! ____@____.com
