Girls friendships

[Gaggleofgirls]

So I'm probably just worrying about nothing but is there anything I should/shouldn't do?

My daughter is friends with two girls, she thinks they're all very close but to everyone around her it's very apparent that she's the third wheel. Occasionally she gets upset by being left out but still seems to hang around them and says they're her best friends (despite them being very clear they come as a pair).
This was the same last year and I was kind of hoping it would have shifted slightly.

Is this just a thing she'll have to learn to deal with? Quite happy to be told either way as I've always been a bit insecure with friendships and I don't want to put this insecurity onto her.

Best idea is to encourage her to find a forth friend to join them!!
Ask her about the other girls in her class, invite one for tea, sound one out to be invited again with the others! 4 works so much better than 3 does at any age imo!!

Primary school female friendships...! Went through something similar last year, found it more upsetting than I ever thought I would on behalf of my DC. I second PP, try and encourage other friendships by having play dates? We had good teachers who also did this and set up a buddy system as apparently lots of the girl friendship groups had upsets.

Thanks I'll ask her about some of the others in her class, see if I can encourage other friendships
