The process of rapid physical changes in adolescence is called puberty. The hormone changes responsible actually begin some years earlier and may produce periods of moodiness and restlessness.
Besides rapid physical growth and these changes include
For girls: menstrual periods, breast development, growth of under-arm, body and pubic hair.
For boys: voice becoming deeper, growth of body and pubic hair, facial hair, erections and nocturnal emissions.
Teenagers may sleep more as growth and development uses a lot of energy
Parents become less important in their children's eyes as their life outside the family develops.
Parents often feel rejected, and in a sense they are. But this is often necessary for young people to develop their own identity. In spite of the differences and arguments the children will usually think a lot of the parents.
Teenagers and their parents complain about each other's behaviour. Parents often feel they have lost any sort of control or influence over their child.
- difficulties in separating from parents
- being perfectionist, and becoming depressed because they can't do as well as they would want to disturbed family life, with early separation from or death of parent.
- an established pattern which may have started at primary school. Such children often have physical symptoms, such as headache or stomach-ache.
- Bullying can also cause all of the above. Most young people do not break the law, but those who do are usually boys.
