To help monitor your child's phone, there's an app called Bark. It alerts parents about websites the kids visit and even images being sent to them to make sure they're staying safe and within the rules established by mom and dad.
"It will flag you. It will flag the parent just to say, 'Hey there is something going on that you should be aware of,'" said a parent.
Parents are urged to set up the parental controls and screen monitoring systems each device has as a way to keep an eye out. Parents can also choose to get apps that help do that.
