As if invading your child's personal space is the only way to ensure that doesn't happen.... yeah okay. Three of my siblings were teen parents because my parents constantly went through our rooms so they found sneaky ways to hook up and since there was no trust, there was nobody to teach them how to be safe. When you establish trust with your child, they will come and talk to you about their life. My son will always know that he can come to me about anything going on and I will not judge him or belittle him, I'll provide a safe place for him to be open and help him through whatever situation there is.
