I'm really not sure where to put this...sorry if it's in the wrong bit.
Basically, our son just turned 2. He goes to nursery a couple of afternoons a week, and recently the key worker told me that he had made specific friends, a group of 4 other children. So we thought it would be nice to ask those children (plus parents obvs) round on the weekend closest to his birthday, not for a full on party exactly but just a relaxed playtime with a birthday cake. We sent out invites via the nursery with our contact details (we don't know any of these people at all) thinking that maybe 2 wouldn't be able to make it so we might end up with 2 kids plus parents, which would be fine. One set has accepted, one has contacted us to say they have other plans, one has not got back to us but has apparently told the nursery that they have other plans, and one hasn't got back to us at all. So it looks as if tomorrow we're going to have just one child plus parents turn up. This is fine, but I'm just suddenly worried that it's going to be really embarrassing - that they're going to come expecting a party and loads of people, and, um, there won't be. There isn't anything to be done about it, but I wondered what other people's experiences had been - have you invited people/kids from nursery to things? Is it a normal thing to do? I'm sort of worried (especially because of the one who didn'tget back to us at all) that we've somehow broken some social ettiquette rule that I didn't know existed :(
