gosh, so I am starting to get a little stressed about this....I kinda thought the Dad would stay at home if he wasn't working and look after the other siblings if there were any. I have hired a Fairy to do games and face painting for an hour and a half - if we go over a certain number of kids the price goes up - but would feel mean saying no that the siblings couldn't have their face painted, etc, join in, do the parents usually let you know how many will be attending or just rock up on the day? This is turning out bigger than I thought....
