I'm pretty sure that our home is like many other young families' homes all over Britain in that the vast majority of the children's toys and books are stored in a large, cuboid, storage system from a well-known Scandinavian company. It's efficient, cheap and it works.
Only it doesn't.
It doesn't work for books.
Granted they fit, and you can actually get a lot of them in the sections, but the problem that I've discovered is that The Boy forgets that they're there. For the vast majority of the time he does not remember about his fifty or so books in the dining room storage unit because he can't see them.
