New York Review Children's Collection!
With books like The man who lost his head and The bear that wasn't, the New York Review offers early onset existential crises, but also, and more importantly, really really great stories for kids. They are all beautifully illustrated, and the books target children from ages 3 to 14.

These are the sort of books I read and reread as a kid. With their focus on delicious picnics, talking animals, and well-earned naps, the heroes of these books inspire affection from the first page.
