I was wondering...

apparently you can have a rough estimate of the mental age of a child by looking at what s/he draws as a person.

So according to that, a child who is chronologically 4-5 years old but mentally much older, 7+ should made quite elaborate and acurate drawings of persons (appart the actual 'execution' which is related to fine motor skills which are more dependent on chrono-age).

So, what is your experince there? Are the drawings of your kids advanced for their age?
