I am a mom of a wrestler that wrestles 8 and under and I have had several conversations with my father about practices and tournaments.

Here is my question to anyone perferably someone high up:
How long should a wrestler at any age practice? Are there
any rules that say that wrestler should only practice so
long so many times a week?
As far as tournaments are concerned my father said that he was told wrestlers that young don't even listen to the coaches on the side that there is no point in the coach being there. How much truth is there to that?

My son is a decent wrestler for his age and I want him to continue as long as he is enjoying it but I don't want to practice him too much or do something to make him lose intrest.

Will you guys please help!?
