More WWYD. DS, 11 and 2 other boys from his class go to an activity once a week in the evening and the parents take it in turns to have then round after school for tea before taking them to it. I've offered to do it this week and I know this particularly suits one if the other mums as she's away at meetings. The day after inviting them I found out from DS that they've been giving him a hard time at school, one of the boys in particular (who used to be his BF) - e.g. having "blank days" where they all blank DS or today not letting him play football as didn't want to get DS germs on his ball, also in the past slagging the food I've made, being horrible about DD's pets etc. It's mainly instigated by ex BF but he's v popular and small school (9 in year) so everyone else tends to follow his lead. I'm going to put a stop to the after school socialising but don't know if I can do it for this week as the arrangement's made.DS also asked if I could speak to this boy's Mum about it but I think this would be really difficult and wonder if discussing with the teacher would be better or if that's just cowardice on my part - DS doesn't want me to tell the school. The boy's mum is lovely and I think would be mortified if she knew what a little s**t her son's being but it's a v small community and I just don't know how to have that conversation without making things really awkward. DS goes to secondary school in the Summer with a much larger group of children so I was hoping things might calm down for a bit after the holidays then he wouldn't have long to go at primary anyway. Any thoughts or advice?
