Adolescents are also developing socially during this time. The most important task of social development in adolescence is the search for identity. This is often a lifelong voyage that launches during adolescence. Along with the search for identity comes the struggle for independence. Your child may: Develop an interest in their sexuality and romantic relationships. Turn to you less in the midst of a challenge. Show more independence from you. Spend less time with you and more time with their friends. Feel anxious, sad or depressed, which can lead to trouble at school or risk-taking behaviors.
