Over years of watching you, your child will have seen your good and toxic friendships, arguments and fun times. They will listen to what is said by you about your friends – the good and bad. So use your experience to teach your teenager about choosing and developing great mates. By learning the skills to be a good friend, your child is more likely to build a strong support network. This is key to their wellbeing and their ability to deal well with challenges that arise through the teenage years.
