Well, inspired by various threads where the consensus view that the only way to make new friends with children / get your children to meet others their own age was to through caution (pride) to the wind and keep asking people, I diligently invited several people / neighbours that I don't know terribly well, but who have children about the same age as DS, to his birthday party. As well as our adult friends, who I do know.
And it seems you are right, people do like to be asked to these things (stands to reason, I'd like DS to be sent birthday party invites). So most of them have accepted (whether or not they turn up, on the other hand...)
The upshot is, though, that there are potentially 9 (probably 6 or 7) circa 3 year olds, plus a couple of younger siblings and one older sibling, plus their parents, plus our nanny and another, oh, six or so of our adult friends (who DS knows) descending on our house. I can doubtless keep the adults happy with cheap champagne, and will doubtless be able to sort out some smarties / sugary drinks / raisins/ fairy bread for the smalls (think afternoon snack rather than sit down meal), but what (if anything) do I do to entertain them? My imagination has so far stretched to a treasure hunt in our garden. I think they're too young for pass the parcel. Do you think there needs to be any activity, or can I just go for unstructured chaos / random toy activity like I did last year?
HELP!
