My son is a little older than yours and almost six feet. At his Bar Mitzvah he was 5 1/2 feet and grew almost 1/2 foot in the year following his Bar Mitzvah. Since then he has grown maybe 1- 1/2 inches and grew all body and started growing facial hair. He's 16 now. We dont expect him to grow much more at this point but will be happy if he did. He definitely had his growth spurt at 13-14.
