I'm organising a small party for an aunt of mine who will be 80 next month. She has no children of her own so it's just her siblings, her nieces and nephews and a couple of her close friends. I haven't included great nieces and nephews as we're quite a large family and it would mean about twenty kids coming along and I wouldn't have the room apart from anything else.
One of my cousins, whose daughter is a single mum, has asked if they can bring her 4 year old as otherwise one of them will have to stay with her as usual babysitters will be at the party.
The problem is this child is allowed run wild, is never corrected, and wants to be the center of attention at all times. I know from previous experience she will annoy everyone while her mum and gran sit there oblivious.
Would it be awful to say no, and how could I do so without being rude?
Why no book recommendations on Mumsnet.
