Common signs of adolescence include feeling self conscious, being preoccupied with one's appearance, and feeling a lot of self-doubt. Other indications of a child entering adolescence are mood swings and rebellion or insubordination at school. Outward physical signs of adolescence in boys include developing facial hair and a more masculine voice. Many girls begin their menstrual cycle during early adolescence, while others begin later. In addition, both girls and boys may develop skin blemishes or acne breakouts, due to hormonal changes.
Children entering adolescence often become irritable and sullen. During this period of human growth and development, some boys and girls may prefer solitary time over family activities. Adolescents may begin to assert their independence, and some may enter a rebellious phase. Other signs of adolescence include becoming embarrassed more easily when confronted by unfamiliar situations.
Although moodiness is common among adolescents, deep depression or suicidal thoughts are not considered characteristic signs of adolescence. If a child appears very depressed, or loses interest in activities and loved ones, this may indicate a more serious issue. Experts claim the teenage suicide rate has climbed dramatically over the years.
A sudden change in attitude may also be indicative of a child entering his adolescent years. Children who were previously cooperative and willing to please may suddenly become headstrong in their determination to do things their own way. As part of the rebellious phase, some adolescents may challenge or test boundaries set by his parents. Many parents are met with resistance when attempting to get their children to do something or behave in a certain manner.
Physical signs of adolescence and puberty are growth spurts. A sudden upsurge in growth may cause a child to feel awkward or clumsy. Some teenagers feel like their feet and hands are too large for their bodies. Girls may notice their breasts begin to develop, while others may wonder why they haven't been developing at the same rate as their peers.
Coping with adolescence may be challenging for some parents. A parent may note that her child seems preoccupied with sex. Although these feelings and thoughts are considered normal by some child development experts, parents may express concern or frustration over this stage in an adolescent's life.
Medicals experts state that human growth and development may affect everyone differently. Some adolescents enjoy their teenage years, while others may find this period challenging. Adolescence and puberty may begin at age 10 or 11 for some children, while others do not enter into this phase until age 14 or 15.
