Talking to your teen
Understand that they may be feeling under pressure to do something they are not comfortable with. If you're worried, one of the best things you can do is to create an environment in the home where your teenager can talk openly about anything that's worrying them.
It's often easier to introduce important topics while doing something else together - whether that's taking a walk or just doing the washing up, it can be more comfortable than sitting down for a big conversation. You can even use stories in the media to approach difficult subjects and find out what your teenager knows and how they are feeling.
Let them know that they can always come to you if they're worried about something, and make sure you remain calm and open when they do. Let them talk, and really listen before you respond. Once they know they can be honest, and get an honest response from you, they will find it much easier to come to you for support.
