There did seem to be any bullying at all in my DD's class up until this year, when it has started with a vengeance. My gut feeling is that the children are getting very bored at break and lunch time (small space to play in, absolutely nothing to do but run around/play tag/skip). The lunch hour in particular is too long - one and a half hours. My DD doesn't eat at school, like quite a few of her classmates, but the ones who do eat at school every day seem to be ganging up and getting up to no good.
Does anyone have any perspective on this, in particular the total lack of constructive activities for 7/8 year olds...
