This issue came up today when I put 2 boys on his invitation list and he said he didn't play with them. He went to both of their quite small parties; one in January and one last July. There were also about 5 other kids whose last parties he went to that I didn't put on his list as he doesn't really play with them anymore. And their parties were large ones with 30 children in halls/sports centres. We have only had small parties at home with 10 kids.
If he invited all that invited him we may not have enough room for the kids he actually plays with (most of whom don't have birthday parties.)
I have this feeling that I should make him invite them but I have no idea why. It would not bother me (unless it bothered my son) if he invited children who did not invite him back. I don't know any of the mothers involved well but I think I would be embarrassed if I thought they thought I was leaving their children out.
Am I just being ridiculous?
