Dd is 11, just started Year 7.
She was enormously happy at her primary school, was in a lovely class and was friendly with everyone but particularly so with 4 other girls. They were a close group of friends and had regular playdates in various combinations.
The mum of one of these girls (let's call her B) seemed to take a dislike to my dd as time went on. Dd was never invited to B's house in spite of B coming to us countless times. When they went on a residential in Year 5, B's mum bought small cuddly toys for her dd and the other girls but not my dd which obviously caused dd a lot of upset. On the last day of Year 6, all the children and parents went to the park after school. I later found out that B had invited the other girls back to her house after the park but not my dd.
They have gone to different secondary schools - two of them to one school, two to another and my dd to a third school. Dd is settling in well and making new friends at school but loves her primary school friends and wants to stay in touch.
One of the girls turned 12 in September and had a party to which dd and the others were invited. B's birthday is in a few weeks' time and I have found out from the other mums that dd hasn't been invited but the other girls are.
This is incredibly mean, right? Dd's birthday is in Feb and I know she will want to invite B. It hasn't dawned on her yet about B's upcoming birthday but I guess she will realise soon enough. The other mums think it's awful and are cross on my behalf.
I really want to say something to B's mum but not sure if I should.
