It doesn’t have to be a strict rule, but once a week is a decent compromise to monitor your child activity in Snapchat by using the Family Center. Snapchat Parental Controls are designed to help parents stay involved without overstepping. Periodic monitoring will keep you informed on whom your teen is communicating with and ensure that everything appears alright. Be open with the communication and make your child understand that it is not about spying but rather safety. Supervision is not any less important than building trust.
