Do you think the pictures that kids draw of themselves and of family members can be telling?

I had my grandson (7) draw a pic of his family. He placed baby sister was on the far left, his other younger sister was also to the left. Then there was his picture. Then his mom and then dad to the far right of the pic.
All the figures were stick figures except the one of himself. His was as big as his dad (dad is 6’4, mom is 5’0 and you could barely see her in his picture) and his was was more two dimensional and colored in blue and green. The body was stylized, no arms or legs.

Then I had him draw each member individually. Two of the members had an X over their mouths.

It was just kind of interesting to study them.
