This sort of thing happens everywhere tbh, state or private, north or south, it’s not unique.
I’ve been to some wild birthday parties- massive tiered cakes like a sweet sixteen, all for 4 year olds 🙄
And yes there are always a few kids who get marked out for not having the “right” trainers or bag or Stanley tumbler or whatever. In schools where parents ignore the uniform policy it just doesn’t work as an equaliser because people will just ignore it anyway and turns into a fashion parade
And yep, loads of fancy cars on the school run.
My kids are in state school for now because it’s fantastic , not an affluent area at all. Along with a bit of showiness there’s also plenty of neglect (which doesn’t meet the threshold for any support) and absolutely shocking parenting which imo is a much bigger issue than who’s wearing Lululemon.
If the big problem is “I don’t like the yoga mums and their big parties” then you do need get a grip. If you have given off these vibes, no wonder they aren’t welcoming.
Maybe your son’s school just isn’t your crowd. You might prefer somewhere with fewer of those visible status things that make you feel a bit out of place, but then someone else would probably feel like the odd one out there too.
Tbh a lot of this just sounds like reverse snobbery. People wanting their kids around the “right kind” of middle class families- showy, but in the acceptable way.
That fantasy school where everyone drives a 2012 Golf estate and feels guilty about their privilege… doesn’t exist.
is your daughter happy?
Go from there.
