The six year old from HELL

My 6 year old plays t-ball. The season just started last week here so every Tuesday and Thursday he has practice from 4:00 pm to about 5:30 pm. This is my sons first year playing baseball and there are about 15 kids on the team. The coach is a policeman who I know and he has help from my sons old soccer coach who has his 6 year old son on the team too. Well anyhow since practice has started from last week Tuesday my son has been complaining after every practice about a boy who is always pushing him or hitting him. I am from the old school that boys will be boys and what not. I pay no mind to him because trying to coach 5 and 6 year olds is a true feat in inself. Anyhow there is this boy on the team who both my husband and I have noticed since the first day of practice. The coach tells him to put down the bat and the kid is swinging it all over. So the coach who is very patient has to go and take the bat out of the kids hand to have it put down. Anyhow the kid is a little hyper. I usually pay no mind to it because some kids are just like that. Anyhow so during practice yesterday I am sitting on my chair talking to the team mom and what not and not really minding what is going out on the field. Well practice is over and we start gathering up our things to get ready to leave. My daughter who is 8 is holding her side like she is in pain. I ask her whats wrong. She tells me old batswinger comes up to her and tells her to "stick em up" and then proceeds to hit her in the ribs with this bat. I didnt see it but my daughter wouldnt lie. Its not her nature. Anyhow I ask her "What kid". She starts telling me the one that my son has been having problems with. I look around the field and that little jackass is no where in site. So my reaction was to pound the kid out but he was no where. So my next thing to do is talk to a the coach. I see he is having a long conversation with a parent...a man. I waited but it was getting late so I left. Still didnt see the little shit around. Anyhow I go home and call my sons old soccer coach who has a son on the team and start telling him what happened. He said funny you should call because the parent that was talking to the coach was complaining about the soccer coach. Apparently my son was on 2nd base and the kid hit a ball and was running ..deliberatley knocked my son over and started to kick him. The soccer coach pulls the asshole kid by the shirt and made him sit on the field in a kind of time out. The asshole kids parent went up to the coach after the practice and was complaining about the soccer coach and that he had no business in doing that to his kid. Oh I was Pissed. I called the baseball coach. The baseball coach told me that the kid has ADD and the parents said he gets hyper. I told the baseball coach that his parents better watch him. If that asshole touches my kids again I am taking a baseball bat and hitting him myself. The soccer coach said the kid is being dangerous and he will be going to the director and making a complaint. I was so pissed. My son is bigger than him but this kid is out of control. ADD or not ..no one should get hurt because of him. Wait until practice on Tuesday.
