What are the developmental milestones of kids from 11 to 17 years old?

As children develop there are multiple milestones that they are typically expected to reach between the ages of 11 to 17. Socially, children will start to spend more time with their peers and begin to try to form their own identity. They will often begin to form new role models, other than their parents. Physically, they will begin to have significant growth spurts and changes associated with puberty. Intellectually, children will start to question rules. They may also develop a sense of "invincibility." 

There will also be large changes during this period from an emotional and behavioral standpoint. In this age group, children may begin to act out or rebel with rule breaking, drugs and fighting. They will be going through emotional and hormonal changes that may lead to frustration;  they want to avoid family and things they used to find enjoyable. Remember, though, that all children will develop at different rates. If you have any concerns about your child’s development, discuss this with his or her doctor.
