DS doesn't draw anything or even try to draw anything. He has drawn a few reasonable faces under coercion but has never drawn a person or an animal or similar voluntarily. It's not that he draws and it's unrecognisable, he just doesn't draw.
He actually has quite good pen control, good tripod grip which he self-corrects, and can trace over letters about 4cm high well which he likes to do. He is attempting to write his own name and, although not well formed, he puts the right number of marks for letters and the letter formation is 'emerging'.
Should I be worried that he doesn't draw pictures though? There are no other concerns about his development.
