My daughter is in year 7. She’s just seen on social media that most of the girls in the year have been to a sleepover together and she’s not been invited. She’s heart broken. I can’t tell her the reason is that when she was in year 3 one of the mums took a dislike to me and has systematically turned many other mums at the school against me with untrue rumours. She is a proper queen bee. So I was excluded from the friendship group of mums which I feel sad about but have other friends. Consequently the girls are always on day trips out in the holidays, play dates, Share after school clubs go on holiday together and are tight. I thought in seniors this would matter less as kids choose their own friends which are not driven by parents friend choices. But it doesn’t seem to be the case it’s awful to see myDD left out because of my friendship dynamics. Any advice ?
