I am asking this for a friend, so cannot be accused of boasting!
Her 2.5 yr old can draw without any prompting a head, two eyes with smaller circles for pupils, nose, mouth and legs (directly onto the head!) with feet.
She was pretty impressed and so was I - my son who's a similar age can only scribble.
Anyone with any links to stages of children's drawing? I know it's definitely above average but not sure about genius!
