Here are some tips on managing your families social media use:

Don’t check your phone as soon as you wake up. Teach your family to be mindful about the content and habits that you allow to influence your life. Sitting and scrolling through social media is not a beneficial way to begin your day. By implementing practices such as not checking your phone as soon as you wake up, you become the one in control of your mind and activity, not technology.
Set time limits. On most smartphones, you can set time limits for screen time and for individual apps. Implement these boundaries to teach your children how to better prioritize time, promote other forms of entertainment, and protect them from the negative influences social media consumption can have.
Have your own social media accounts. By doing so, you can use them to follow and monitor your child's viewing habits and you can remain involved in your child's online life. Though your child may not like it, this gives you a front-row seat. You can see what they post, who they’re following, and monitor their media use first-hand.
Have fun, screen-free family time. Go out, cook dinner together, or have a game night.
