madeleine, how I agree with you! Books are the backdrop to my life. I am passionate about libraries, read at every opportunity, and have done my best to pass on my enthusiasm to my children, grandchildren, and those I taught.
Books can be powerful and subversive, or comforting and diverting - and, with a library card, completely free..
Where I taught, WBD was celebrated by everyone coming in their nightwear , as a nod to " a book at bedtime" - so no cost to parents. If they wished, the child could bring a favourite book to talk about, but this was an option.
I loved seeing my GC setting off as Supertato, The Worst Witch, etc.
The secondary school my 11 year old attends suggested authors as the theme.
My GS went as Adam Kay.
As you can tell, I'm a WBD fan...oh and the token gives every child the chance to own their own book.
What's not to love?
