Just found this thread on Active threads. So pleased you updated.
I'm so pleased for you and your dd who sounds lovely. You made a great decision.
I sent my eldest dd to a school where she had no Primary friends. It was her choice as well as mine. She was confident and happy in Y6. I was expecting her to flounce in and flourish immediately in Y7. It didn't happen.
She found friendships hard to break into. It took her a while to make any connections. I was desperately worried and I was lucky that she wasn't being bullied so I can only imagine how you felt OP.
After a month or so I contacted the school. They were really helpful and reassuring. They spoke to her, got to know her. Her Y7 tutor urged her to join the Y7 drama club. That was the key to it. There she found interesting friends that spanned the tutor groups. From there, she regained her confidence and went forward.
She's now in Y9 and very happy. She's currently in the lead role in As You Like It in a few weeks!
I think a PP summed it up when they said the measure of a school is how they respond to problems. 'kick a Ginger day' ffs?????
My ds just started Y7. He too had no-one from Primary there. I braced myself for difficulties, but I was lucky this time. Only after few lonely lunchtimes and he seems very happy. Joined drama club (after my dd recommended) and football club (playing football for the first time ever!).
I wish your dd all the best OP. Being happy is one of the best foundations for doing well. She obviously has a very supportive family behind her so I'm sure she'll flourish
