My son is only 6 years old and is such a sweet kid he has been hit,scratched,kicked spat on you name it.The school usually calls twice a week to let me know he has been hurt and the other child did get in trouble.It's usually the same 3 kids, I understand kids will be kids and boys are rough but come on!!! He comes home with bloody scratch marks on his face and bruises,it's sad to see. I have talked to the principle several times about it and told her,Im tired of this,I entrust my child with you and every week my child is getting hurt and it seems nothing is being done.What should I do?
