Mommo Design has a bunch of inspiration for girly reading nooks. These quiet corners contain fluffy pillows, rugs, cushions, usually a canopy, and of course lots of books. I think the idea is very cute and I'd love to do this for my daughter's room.
this is another idea I saw in that client's house. Useful for stuff besides babies, of course. They don't want to stay all day in those little baskets anyway. Sweet idea for baby organization in a closet. You could even use it as a changing station.
