There is hope @Jerseyshore12...
I had similar a experience to you for the first 3 years of primary.
My ds was happy and had friends but I found the parents very cliquey and hard to get to know. It was like they suddenly all knew each other after the first week in reception and had loads to talk about while I was still stuck on occasional small talk.
I wasn’t too upset as I had plenty of friends outside school, but it really did make me feel awkward! I would smile and say hi! And people would reply, but that was it, no other conversation, and they’d tootle off to their group. I resigned myself to standing on my own for years and ended up getting later and later to avoid it!
The thing that did upset me was that my ds was never invited anywhere because I wasn’t part of the clique. We invited a few friends to ours but none ever reciprocated. I didn’t know anyone enough to dare suggesting meeting up in the holidays.
The turning point came when I started booking ds into a few clubs outside of school. A couple of his classmates were at these clubs and he started to get really friendly with one particular boy who had loads of shared interests. I got chatting a bit to his mum (who was one of the parents in the “clique “ and she was lovely and very friendly. We have done play dates since and ds is very happy.
She has said that despite being friends with a lot of the mums through her older children, she was always worried that her younger one didn’t fit in well so is pleased he has finally found a friend.
I hope things start working out better for you, just keep smiling and saying hi. Things always change through the years, kids will fall in and out and you’ll probably find the “cliquey” group may move on or splinter off a bit.
