Barron is a beautiful boy. He has definitely had a growth spurt in the last few months. I believe he will be 6’6” by the time he is 21.
I am from a family in which many of the women are 5’10” or over, and the men are mostly between 6’ and 6’6”.
It’s amazing how children grow differently. It is very hard to predict how tall a boy or girl will be as an adult by looking at their height when they are 10 years old.
