Young people are busy working out who they are and where they fit in the world. You might notice your child trying out new things like clothing styles, music, art or friendship groups. Friends, family, media, culture and more shape your child’s choices in these years.

Your child will probably want more independence about things like how he gets to places, how he spends his time, who he spends time with, and what he spends money on.
