My eldest ds (age 4) is a little on the shy side but is keen to join in with the other kids in school. With this in mind our lovely nanny suggested he invite some classmates round after school tomorrow for games in the garden, snacks, etc. I agreed and was more than happy to let her get on with organising. As this is my pfb, I'm not quite in tune with the unspoken rules and protocols of schooly circles. So i just wanted to check: is it OK to give invitations to 6 of ds's classmates, or is it expected that the whole class be invited to any parties? We have a pretty small garden so inviting 26 kids really wasn't an option.
