She is nearly 11, and through 2 major clearouts she still has about 2 entire bookshelves full of the picture books we read to her throughout the years. (eg Giraffes can't dance, The Gruffalo, Sharing a Shell, all that ilk). We did a major prune, only keeping the impossibly special ones that we can both remember poring over for ages, pointing out lovely parts of the story / pictures. That still leaves us with 2 shelves full. She's never going to read them again, nor am I. But they played a huge part in our lives, and it seems awful to just get rid of them. But its 2 shelves full!
