It was my DD's 5th birthday last week (not at school as we're in Scotland) and she invited her nursery friends and children that she plays with who are neighbours. I invited one of the children whom she's friendly with who lives a couple of doors down and the mum rsvp to say her dc was was coming. All in all 20 children RSVP'd and I made party bags etc, bought food.
Anyway on the day the mother brings along the child and four cousins in tow whom my DD has never met! i naively asked if the children were going somewhere while her child was at the party and she said no that culturally she expects to be able to bring along extra children as it's a celebration.
AIBU to think you don't bring uninvited children to a party especially when they've never met the child whose birthday it is?! I don't mind making up party bags etc and there was plenty of food but it's the principle!
