Adolescence is the time between childhood and adulthood - between the ages of 12 to 18 -- that is marked by growth and change, and physical and emotional development.
The physical and mental changes are predictable, but that doesn't make this age group any easier to understand and communicate with
At the onset of adolescence, children develop the ability to understand abstract concepts, question values, develop a more mature sense of identity and learn to establish personal relationships. The physical changes at this age are dramatic, as boys and girls gradually grow into men and women.
