Developmental Milestones - Young Teens (12-14 years of age)

This is a time of many physical, mental, emotional, and social changes. Hormones change as puberty begins. Most boys grow facial and pubic hair and their voices deepen. Most girls grow pubic hair and breasts, and start their period. They might be worried about these changes and how they are looked at by others. This also will be a time when your teen might face peer pressure to use alcohol, tobacco products, and drugs, and to have sex. Other challenges can be eating disorders, depression, and family problems. At this age, teens make more of their own choices about friends, sports, studying, and school. They become more independent, with their own personality and interests, although parents are still very important.

Here is some information on how young teens develop:
