If you think your pre-teen or teen is safe against pedophiles on the internet, think again. Although they will use the computer to get to your child, they can also use texting and cam on their cell phone or have communication through the local library. It only takes one click. One picture. Pre-teens and teens are more vulnerable to pedophiles when their self-esteem is extremely low, or they are very lonely or feel unloved. Make sure to communicate as much as possible with your kids and help them make wise choices.
