An Update: Last night my son started training again.
. I think it may been his sudden growth spurt and the "control" issue that you all referred to that was making him anxious.
Also there was an incident at school yeaterday where he had to defend himself against a larger Bully. This kid attaked him from behind and tried to put him in a headlock.(he delt with the situation and the teacher who Rang me said it was not his fault and he handled himself well against this known troublemaker) It was as if this incident gave him the confidence to recomence training.
I talked to our instructor a week ago so he knows what is going on and his advice was to just give him time. So when he returned to training he was met with encouragement, and the fact that he has been training at home, he will be allowed to try for his first black tip at the end of the month .
