DS loves to draw (with real pencils and crayons, not etch a sketch etc) and I would love to find him something he can comfortably draw with while strapped in his carseat.
We have the My Travel Art Desk from ELC which works okayish (so long as DH is driving; I need the seat too far forward) but I'd really like something that would stay put on his lap and that he can rest on and apply pressure to the paper without dropping everything every ten seconds.
