It must have been very hard on you as well as your daughter when she told you how upset she was about being bullied. You want to think that your children's first experience of school is a good one. I suppose from the teachers point of view, it takes a while to determine if a child needs referring to an educational psychologist like the little boy in question. Not that it is much comfort to you in the meantime.
Did you talk to his parents? Were they aware of your daughter's feelings? It must have been hard on them too. Who wants to think their child is causing problems?
The situation I found myself in was different to yours but in answer to your question about controlling my son's behaviour here goes:
When I became aware that some of my friends were worried about my son's behaviour to their daughters in and out of nursery I made an appointment with his teacher(unasked)to get advice. I asked her a number of questions: Was my son hyperactive? (despite the fact he sleeps like log), Was he turning into a bully? Was there a problem between him and these girls because parents were expressing concern? did he need any extra help? Was I controlling him properly?
I asked the teacher not to spare my feelings. I also went through these questions with my son's baby sitters who knew all the children concerned and other outsiders whose opinion I respected.
The verdict form them all was: He is lively, not hyperactive. He is usually very kind and caring and plays well at nursery with girls and boys, including the girls in question. These girls are excitable and so is your son. Sometimes he gets carried away and if they are argueing, he will hit out at whoever is there, boy or girl. There is no need for any therapy, this is normal development in a 3 5 year old. He's a very boyish boy and has strong emotions. Gradually he will control them better. He is not the worst behaved in class. He is not a bully and does not egg others on to be bullies.
I told the teacher how I controlled him when we were with other children and she said there was little more I could do apart from keep on doing them - I was doing all the obvious things eg:
Calmly but firmly telling him to stop and meaning it. Telling him to say 'sorry'. Taking away or threatening to take away a treat, or promising a treat for good behaviour. If all this failed, cutting short his playtime by taking him home.
In retrospect I don't think I was always good at the above, but he was my first child I was having to learn about behaviour control as I went along.
Trying to be tactful as I could, I spoke to the daughters' parents, my friends, about the teachers comments. They were not convinced. And of course it was easier for me to say, 'no action needed' My child was not being hit. They did not feel the teacher's promise of monitoring the situation went far enough, hence their requests for my son to be moved or his nursey time limited to a half day. Neither of which took place. To be honest I began to feet as if I was being bullied too - by these daughers, parents.
I began to think about how my son behaved with some of my other friends daughters away from nursery. No hitting, they got on fine.
I came to the conclusion that my son, and probably the daughters, too, were picking up on the tension between the nursery parents and myself.They knew we were getting wound up about the whole thing and were not presenting a united front when doling out discipline. To these parents, my son was almost always going to be in the wrong and I felt torn between my loyalty to him and my friendship with these parents. Just ignoring my son or telling him off was not going to change his behaviour. He needed some positive attention too. That's why I told the parents that I thought it was best if our children did not meet for a while so things could cool down, and my son could grow up a little, but I would hope our friendship could continue with adults only meetings, as it always had been.
I felt I was backing down and being considerate. (What else could I have done? moved my son to a different school?) But the parents saw things from their daughter's point of view only, and cut off social contact with me.
It all worked out in the end. School saw to that, as I said previously, and now we are all, adults and children, very good and well-behaved friends again
