My 3 year old has just been invited to his first proper birthday party (well he will just be 3 then, the week before his friend's party). I don't know whether I am supposed to stay or just drop as I have no prior experience of these things! I know he would be fine as it is a bunch of his nursery chums who are thick as thieves, although I don't know the parents. I can obviously ask on the RSVP but wanted to pass it by MN first to get a heads up on the protocol....it doesn't say either way on the invite. It's in his own house, not a venue. I suppose I'd rather just drop, but also thinking he hasn't been toilet trained all that long!!
