All teenagers are different. But many like to spend their free time doing things like shopping, going to parties, being with friends, using technology for games or other online activities, social networking, texting, watching movies, reading and going to the beach or park.

Teenagers are also spending an increasing amount of their free time in structured extracurricular activities such as arts and sports. And they often feel bored with unstructured spare time.

One of the joys of the teenage years is discovering the things you have in common with your teenager, or new things your child might open your eyes to. Spending free time together is a great way to stay connected with your teenage child.

Sometimes teenagers will just want to spend time by themselve, not doing very much. Solo free time is fine, if it’s not all the time and is balanced with spending time with friends and family.

It’s also OK for teenagers to feel bored sometimes! Being bored can motivate them to find something creative or new to fill their time.

So parents shouldn't decide how teenagers spend their time and should only remind them. It will be better!!!
