sunnygirl, thanks for your comments too. So sorry to hear what a devastating affect it's had on you. It's a pile of crap to say name calling doesn't hurt for you.
Well, just to bore you silly, this is the final version of the email I sent
Good Morning XXX,
XXX told me just before the holidays that he had been getting picked on and feels bullied by 3 girls in his class. He outlined what has been happening. He then told me he had spoken to you, and that you had spoken to the girls in question.
I was hoping that after the holidays things would improve, but unfortunately, it seems not.
XXX has been coming home miserable, and saying he has had a bad day at school.At first he wouldn't tell us why. It is troubling him greatly (he used to be very positive about school, now he isn't, he is increasingly anxious, and now wants to share his brother's room, he is reluctant to go to school, he worries what the girls will do that day etc).
While name calling, general niggling, annyoing behaviour such as shoving, taking the football etc etc may seem trivial, the incessant nature, and from not 1 but 3 people takes it to another level.
I would appreciate it if you could have another talk with the girls and consider changing his seat, so he is no longer sitting with 1 of the girls. Also, I think it would help him if you (or you and I together) spoke with him about how he can best deal with the situation. Clearly just ignoring it isn't working, and some things, like shoving can't be ignored.
I would also like to meet with you (or talk over the phone if it is more convenient) to discuss this matter. I'd rather keep it separate from the conference next week, as I don't want the whole meeting swallowed up by this issue.
I appreciate your help with this and look forward to hearing from you,
will let you know if I hear. Thanks for reassuring me I'm not being pfb about it.
