DD is in reception and there are only 8 girls in the class, one girl has just had a b'day party and only invited the girls from the class (not the boys), all the girls that is apart from my DD....it turns out that she was the only one not invited. I just wouldn't do this if it was my DD's party as I would be worried the one left out would be upset and I wouldn't want one child to feel upset and left out. I really want to ask the mother why she did it and if there is a problem between my DD and hers - do you think it's ok to ask this or should I just leave it. I feel so hurt and upset for my DD.
