I sent my boy to the kindergarten when he was 3y/o.He enjoyed the life there ,never cried because of not seeing us. He is very independent ,likes to help the teachers to do things; likes to play with other kids. But if he saw them playing toys ,he definitely will grab it by pushing or biting the kids. Several kids been bitten one or twice by him during the last semester. Those parents complained to the teacher but none of them shouted me face to face. Ps , I never spoiled him too much , never beat him because of his biting habit. I kept explaining to him how bad to bite others, if he keep doing this , nobody will play with him any more, he’ll not allow to go to the school, ect. Normally I have to keep telling him “ look at me ,I am talking to you.” Because most of the time he wouldn’t listen, still playing his toys, or sometimes he will give me a kiss and back to his games, but no matter how anxious /angry I showed to him, he just doesn’t care /forgot, and do it again the next day. Fortunately this semester he is making a big progress – haven’t bite any body till now one month. But few days ago, he scratched a boy left a mark not a deep one about 1cm long on his face. The boy’s mom rang the teacher that night about 23:30 pm asked for my number ,The teacher was half awake couldn’t find it and she doesn’t want to give it to her. But I think it’s better I talk to the mom on the phone( she rarely go to the school). So she got my number and rang me straight away : You son bit my son once and now he scratched his face .I couldn’t forgive him. If he hurt my son again, I’ll go to the kindergarten to beat him! And you should beat your son so he will remember don’t hurt anybody any more! Then she hung up. During the phone call I tried to explain I understand how she feels and I’ve been trying to help my son to be nice but she won’t give me a chance to talk. Now what should I do with this 4 y/o naughty and the angry mom?
