Puberty and Growth
T he bridge between childhood and adulthood is a period of growth and change called puberty. There seems to be no standard pattern for the physical changes of puberty. Two boys of the same age who have been nearly identical throughout childhood may appear to set off along entirely different paths of physical development as they enter the teenage years. One may quickly shoot up to a height of five feet eight inches within a couple of years while his companion lags for a while at preteen size, then begins growing into a six-footer. One may develop a heavy beard in his early high-school years while the other boy will have no use for a razor until he is in college. However, both boys are normal youngsters, and each will eventually attain all of the physical attributes of adulthood.
Similarly, one girl may begin menstruating in her 11th year while a classmate will not experience her first menstruation until she is 16. One girl may need a bra while still in grammar school but her friend will fret about a small bustline for many years. But both girls can look forward to normal womanhood. Each has an individual pattern of development, and if there is any rule of thumb about puberty it is that each youngster has his or her own time schedule for the transformation into a mature man or woman.
