When do the big parties stop?

[Thisisanawkwardwatch]

Dd, is 5 this summer, we’re doing a *Big full class party at a play place for all
her classmates and friends from outside of school. It includes everything-cake, themed decor, hire of the place, food, goodie bags, ballon maker, glitter tattoo/face painter etc.
This is fairly standard where we are (we’re abroad) and comes to around €400-€500, this plus buying her presents is crazy to me and we could have a small holiday for this.
However, most of her friends have similar, she’s desperate for a big party and I’m doing extra hours to pay for it.
Her birthdays in the past have been, a little garden party for my parents, immediate family etc at age 1, age 2 was during lockdown so just us, but lots of balloons, bubbles, presents, a lovely cake etc. Age 3 was a party in the park/playground with around ten friends and last year was with immediate family again, with pass the parcel etc and a meal out with pizza and ice cream (with family)
This is why I want to do the big friends one this year. How many years do they tend to be parties like this? I’m expecting next year to be pretty similar, does it change at all at 7 ish? When does it become a smaller group for say the cinema/bowling etc or what else does it become?

We did whole class parties once when they started school although the norm around here are whole class parties up to age 9. That said, in one of my DC's year, half the class have never had any party other than family presumably. In another DC's class, the majority had parties, most of which were whole class parties. I imagine that was more a response to covid than anything else.

After that we reduced it to approx 15 kids per party. Around here the birthday activity costs approx £20 per child so £300 per party which included food but not the birthday cake..

I agree with other posters. If having a big birthday party, the birthday presents should be limited according to your budget.

Hall+bouncy castle round here is more than £150

I wouldn't start it, then you don't have to stop. That's a ridiculous amount of money to spend. And by the sounds of it you can't really afford it. Just get DD to chose 5 friends (she's 5) and do a party with them.

She'll have just as much fun, if not more fun, with people she really likes.

You dont HAVE to do anything
We did it for reception as it was fun but the next year(s) it became a small group .
There are no rules for parties op.
