The numbers on the left are Will's ages and heights. To the right in blue are Sam's. I don't know if you can read it, but Sam's last height is 6.8. 6 years 8 months. Don't worry. Will is a little taller. We just didn't mark his height. But compare Will's 6.9 to Sam's 6.8. I keep telling them both to quit growing, but they just don't listen.
