Son hates dressing up today will be awful

[Inliverpool1]

Do I persuade him to wear the hat in the cat costume I’ve bought against his better judgement or sending him in uniform knowing everyone else will be dressed up.
This nonsense raises my blood pressure every bloody year

When DD was 7 she went in in a hoody and jeans. Her teacher asked who she was and she said - "I'm Tracy Beaker - don't worry I've brought my attitude"

There's a boy in DD's class who won't dress up. He just comes in home clothes when it's dress up day. His mum usually sends some kind of prop (which he refuses to carry) just to show willing. Even in the school play he was barely in a costume.
