During the Puberty growth spurt at the end of childhood and the beginning of adolescence. Such comments as” My, how you have grown since I last saw you !” are evidence of how others notice these changes. The pubescent child is also well aware of the changes which necessitate a constant shift to larger clothes and a relearning of muscle skills to counteract the awkwardness of the bones and muscles. Elizabeth (1968).

Puberty is an overlapping period. Because it is customary to draw the line between the childhood and adolescence at the time when the child reaches sexual maturity, the period of puberty must be regarded as an overlapping period, a time when the child is no longer characteristically a child because of the changes in his body and his behaviour, nor is he yet an adolescent. Until he is sexually mature, the individual is known as pubescent child or preadolescent; after he becomes sexually mature, he is known as a young adolescent.  Puberty is relatively short, lasting from two to four years. Puberty is a period of rapid physical and psychological change. It marks the transition from the childish body, a childish outlook of life, a childish form of behaviour to a mature body and to more mature attitudes and patterns of behavior. Elizabeth (1968).
