Hi 2020Mom, I am the aforementioned Caco. I will be sending you a PM, please look for the red circle near your name up top to access your private messages.
However, before I do that let me ask how big your son is? How far into puberty is he? Is he 6'2 and 200 pounds or is he 5'8 and 140 pounds? This will matter greatly in the advice you receive.
