I thought that book day was to encourage the children to read..it's turning out to be a bit of a headace in our household. Last year the children just had to dress up as a character in a book. This year they have to dress up, but also take in 50p for the school, and donate a book.
My ds (5) hates the whole idea of going to school in costume and wouldn't choose a book, so I'm left with trying to persuade him to choose between jeans/top, or one of our normal dressing up costumes (police, firefighter etc) in the morning.
