What do you do with your children's books once they've finished with them?

Do you stockpile them? I voluntarily run our Primary School library and have a good budget from the PTA for books but I try to buy books from charity shops so that money can be used for other things.
Several times a year I ask via our FB page for donations of used books. I'm lucky if I get more than 20 books from a school that has 300 pupils.
It's very unlikely that a child wants to read any of the books from the Tom Gates, Diary of a Wimpy Kid or Dork Diaries series more than once so why do parents hang on to them?

Please, have a sort through and donate books to your school's library.

I keep them for younger dc

Pass them in to friends' children.

Honestly, I'm planning to keep them. DC are only 2 and 4 so haven't really accumulated that many, and 2yo DS has destroyed loads a few.
But my PIL's kept all DH and SILs toys and books and my DC love playing with them/reading them when they go to visit.
And I love getting all nostalgic about fisher price activity tables and Ladybird Early Readers and Puddle Lane books.
