A bit of background: ds (7) has problems integrating with his peers. We thought he might have an ASD but when assessed by an Ed Psych in June the conclusion was that he is about 7 years ahead of his peer group and his difficulties stem from that. We have worked with the school for 3 years to help ds. The school are quite clear that he is not an agressive child, just loud, and are aware that he has become the class scape-goat and is frequently picked on by other children (although he can stick up for himself).
The current issue is that there is a very "growm up" girl in his class. She made lots of comments to ds that he was just not able to deal with. As far as I (and the school) am aware, he called her names and she called him names and they mutually dislike each other. The girl also said pretty unpleasant things to my younger dd. This was all in the last school year, now they ignore each other.
It turns out that since, on several occassions, the girl's mother has made excuses to come into school and has waited for ds in corridors to tell him off and has called him "horrid boy" and "bully" and similar. On the last occassion she did it in front of many of his class mates and they told me about it. There is no suggestion (even by the mother) that at any time that ds did anything other than call the girl names.
Clearly I have told the school and they have talked to her and she admits it and sees nothing wrong with it. I am so angry I could cry - we have spent so long trying to help ds fit in and I feel like she has just undermined it all. I really do want to scream at her.
Am I over-reacting or am I being reasonable?
