I should add that it's sort of hard for me to buy kids books. My dad was in children's publishing for years before he retired. Before then he supplied me with literally many hundreds of kids books. I have a large library for the kids from board books to kid novels. Hundreds and hundreds of titles.
he had friends at all the different houses, I used to get readers copies, etc.
It has been quite a shock to have to
pay for books
Still, I can't help it (I'm worse with books than my wife is with shoes
).
