So difficult !
I’ve had similar with my 13yr old with a girl she’s known since nursery. It was bad in y3/4 but those were Covid years and in y5/6 they were separated. The school clocked what was going on and I just said my child needed space.
The other girl is fussy and only likes a tiny number of other kids. The mother is also fixated on my child.
It got really bad when they started in high school and were not in any classes and the mum was completely over invested in their ‘friendship’ and started contacting me asking info about what my child was doing all the time and trying to arrange meet ups !!!
I’ve completely distanced myself from her and if she contacts me again I am going to say in plain English that I’m concerned about their fixation with my child and I’m getting a restraining order!
I should’ve sorted this early as child was really sick of it.
Can you keep your child off for a few days saying she feels coerced into hanging about with this kid?
Can she go elsewhere at break with another child - location in the playground or a club ?
Can you request a class move ?
She needs to learn to say ‘oh I’m playing with x today’ or maybe hang out in a group. Can the school give the other girl a different activity at breaks? This is so hard for kids to navigate though. There should be a word for this. You don’t have to like & play with everybody and not liking someone is not bullying !
She could learn to parrot ‘oh I play with you a lot I’m going to play with someone else today’ and with physical touch just say ‘stop it I don’t like it’. To be honest I think it wouldn’t be a big deal if she was more direct to her what’s the worst that can happen ? The school will call you and you can explain once more that she’s unhappy & smothered with all the over attention.
