Drawing Pictures

The kids spent a long time, maybe a half hour, drawing pictures the other day.  In the photos below, you can see Sam starts out in one seat, and each time he got up to show me his picture, Vivian would immediately take his seat, until she had sat in each spot at the table.  

Sam draws our house, while Vivian forgot to use her paper.

Not sure if she's looking at his drawing or coveting his seat.

Drawing the planets (each planet has a person on it?), while Vivian focuses.
