one year ago, our son became burned out. He told us a week before subs he didn't want to go. This was really hard to take, he is a good little wrestler. We accepted it and he sat out last year. This year we have seen a big improvement! He doesn't complain about anything, he looks forward to going and seems to be enjoying the sport again. I think it was a good thing for us.
We now let him decide his weight (which we monitor) and the tournaments he would like to go too. IF he decides ever again he wants to sit out we will support that decision. Good Luck with your situation!
