Boys continue growing until age 17 or 18. Boys and girls grow about two inches per year until they reach puberty. Then they each have a growth spurt that lasts a year or two. During the growth spurts, boys grow a little faster than girls. Girls reach puberty (on average) about a year before boys do. Girls also end puberty earlier than boys.
Growth Spurts in Boys. Growth spurts in boys and girls are very common occurrences as they go through puberty. It has been estimated that young males can grow up to 9 centimeters a year during puberty, and females can grow up to 8 centimeters a year.

Equipping oneself with the knowledge and understanding of what is happening will help your kids overcome this confusing period.
