Great discussion here, I could learn from you all of your experiences. Looking back, all those wins and accolades were immaterial in LL, and parents should pay extra attentions to arm care as the little kids would not know the consequences at such a young age. The kids usually try to please the adults and as a result would play hurt when told to, they are too young to speak up. Still remember when son came to me about pain in the elbow when he was young. He then showed me if he throw when this other arm slot, it would not hurt, etc.. I let him pitch another game or two but the problem was still there. So I read as much as I could and sprung into action. No more pitching, had x-ray, PT, and MRI at the end just to make sure everything was ok. Then rest for another 6 months. Each time when son was asked to join a travel team, I hesitated. I was told many times that son should join the best competitive tournaments as much as possible but I still hesitated. Looking back, I am glad that I did hesitated and son did not join any of the travel teams. My take of the debate is that the younger the kid start pitching, the more closely the parents need to pay attention to overuse. Take every pain and ache that the kid is complaining seriously. Don't tell them to rub should sand/mud/dust on the arms and everything will be ok - it doesn't work scientifically.
