DS turns 7 in a couple of months and we're starting to make celebration plans. He hadn't had a big party before and it isn't in our budget to do one this year, but we're thinking of having a small one at home with just a few of his closer friends (max of 10).
The thing is, he's attended a lot of parties of classmates in the past year or so (since covid restrictions allowed) where his whole class has been invited. As such, I feel as though this is the expectation. Also, many of the parties were for children who he isn't particularly close to and likely wouldn't be among those invited to his smaller party.
What is the etiquette on this. AIBU to not invite them. And how do I go about inviting just a few without upsetting other children/parents?
