This is probably a bit more of a WWYD than an AIBU. DS (2.5) plays with a little girl who he met at a playgroup. Her nanny and my nanny hit it off and they have been meeting for playmates etc for about a year. I have met her parents once, at his birthday party, and have exchanged texts with the mum but don't know them well.
I invited this girl and his nanny round next week and the nanny has said that she is really sorry but the mum doesn't want her to organise playmates with DS. She said that DS is a bad influence and the girl misbehaves after seeing him. She said that she is going to try to change the mum's mind.
I am so, so sad about this. DS and this girl really like each other. I would understand if he was hitting / pushing / biting / being unkind but he isn't doing any of those things.
My understanding is that the mum is fairly extreme in some of her views (so her daughter is not allowed to do quite a few things) but I don't want to go too much into that here.
What (if anything) should I do?
