Our childrens' spaces workhouse, the IKEA Expedit, really can do it all. If you're lacking a closet in the baby's room, use the Expedit as a closet for your baby's clothes.
We spotted this alternative use of the Expedit as a mini closet. It's just a simple 2x2 Expedit unit without the inner shelves but with the addition of a closet rod. The 2x2 sits on a 2x8 Expedit, which saves on floor space. Check out IKEA Hackers for a detailed shot of this closet.
