I second the flip-out sofa - best present we ever got DD, she gets so much use out of it. And even though they are meant to be for older kids, she LOVES (and is very good with) books that have the sliding parts/tabs and flaps. Also, musical instruments like xylophones, drums and tambourines, an easel with big stubby crayons/paintbrushes and a little, indoor/outdoor slide with a platform - these all get lots of use.
