Oldest is starting reception and will be 5 in a few months so I feel I'm now at the pointy end of this ettiquette question.
We've done one playdate where another child was dropped at mine but I knew the mum and child quite well in advance and she had an older one so it was harder to stay. Are there any general ettiquette rules? I've been to a few birthday parties of older kids where it seems like most parents drop but a small volunteer cabal of parents remains - do you just sort of ask for volunteers for that sort of thing? I'd certainly be just as happy not needing to feed and water one adult per child at kids' parties...
