Normal Development: Early Adolescence (12 to 14 Years Old)
Adolescence is divided into 3 stages: early (12 to 14 years), middle (15 to 17 years), and late (18 to 20 years). While certain attitudes, behaviors, and physical milestones tend to occur at certain ages, a wide range of growth and behavior for each age is normal. These guidelines show general progress through the developmental stages rather than fixed requirements. It is perfectly natural for a teen to reach some milestones earlier and other milestones later than the general trend.
Physical Development
- May experience growth spurt (girls usually develop 2 years
earlier than boys).
- girls: changes in fat distribution, pubic hair, breast development; start of menstrual period
- boys: testicular growth, voice changes, pubic hair, "wet dreams"
- May try to experiment with body (masturbation).
Emotional Development
- May be moody.
- Struggles with sense of identity.
- Is sensitive and has a need for privacy.
- Is anxious due to increased social and academic stresses.
- Starts to look for loving relationships outside of family.
- May be opinionated and challenge family rules and values.
- May try to "show-off."
Social Development
- Becomes more self-sufficient.
- Usually seeks out friends with beliefs and values similar to those of his or her family.
- May be preoccupied by appearance.
- Gets interested in romantic and sexual relationships.
- Influenced by peers about clothes and interests.
- May be influenced by peers to try risky behaviors (alcohol, tobacco, sex).
Mental Development
- Mostly judges based on concrete rules of right and wrong, good or bad.
- Thinks in terms of the present rather than the future.
- May start to think abstractly and about complex issues.
If you have any concerns about your teen's own pattern of development, check with your healthcare provider.
