Birth, Infancy, and Maturation - Six years to adolescence
The years from 6 to 11 have generally been regarded as quiet years as far as emotional development is concerned. Many of the tasks of earlier childhood have been completed, and the relatively stormy years of adolescence have not yet begun. A child's interests begin to turn more and more away from his family and to other children his own age, usually children of the same sex. At this stage, a child's interest in learning is broad and intense.
During this period children begin to be more and more individualistic. Some are solitary, others sociable; some are athletic, others not. One likes only other children, another prefers the company of adults. Some children have imaginary fears that disappear with age or when the fears are discussed with an adult who can explain how or why they originated.
Curiosity about Sex
The child's earlier curiosity about naked people may change to a concern about being clothed and being with people who are clothed. Questions about sex should be answered simply and truthfully.
Adolescence arrives anywhere from 9 to 14 years of age. A girl usually enters adolescence at 10, a boy at about 12. Adolescence lasts through the teens.
In female children, there is growth of the breasts and nipples; the pelvis matures, and the external genitalia develop. Axillary (underarm) and pubic hair appear. On the average, girls have their first menstrual period around age thirteen, but it can occur between 10 and 16 years of age. Be sure to explain menstruation to your daughter before the beginning of adolescence.
In male children, the penis and testes develop. Facial, axillary, and pubic hair appear. The voice begins to deepen.
In both boys and girls, there is a rapid growth in height and weight which is related to sexual development. In general the average height of the adolescent is double what is was at age two. See Ch. 3, The Teens .
