DS is 4 and can't draw at all. Not even a smiley face - he can do a circle with a few dots in it but that's all. Mostly he does scrawls. Today we met a boy in the Tate who was five and was drawing a crocodile in a pond with a snake! And his friends all seem to be able to draw something. Ds can't write either - wondering if it is all related in terms of recognition of shapes etc. Any views?
