I moved out the toy box (most of his toys are downstairs in the living room now creating chaos) and switched it out with a wagon that Meredith's fiancee gave to Drew. Our other Radio Flyer, the one Kim and I used growing up, is what Drew uses when he's playing outside.
The front panel easily slides off so Drew can access all of his books easily. So far this has resulted in less books thrown everywhere and he can pretty easily recognize his favorites and pull them out.
Doesn't that make you melt?
