DS is in year 2 but doesn't really get invited for play dates at his friends houses. He is happy & confident & described by his teachers as being popular. Most of the mums in his class are at school pick up/drop off every day so have got to know each other really well but I'm only there 1 day a week so haven't become part of any of the cliques. It seems that most of the play dates are arranged based on how close the mums are rather than who the kids play. DS has been invited to the house of a boy whose mum I talk to quite a bit even though they don't really play with each other in school but he doesn't get invited to the friends he plays with all the time. I've invited some of them round a few times but the offer has not been reciprocated. It makes me feel bad for him especially when he says things like 'why do I never go to ?? house?' I know i shouldn't but I can't help but take it personally & feel like its my fault as I'm not close to the mums of his best friends. I don't know what I can do about it but I don't feel like I want to keep inviting these boys round if DS is never asked round to theirs....
