The 10 Warning Signs

• 1. Meltdowns at shutoff: crying or rage every time screen time ends.
• 2. Loss of interest: no other activity is enjoyable anymore.
• 3. Constant preoccupation: talks about it even when not using it.
• 4. Tolerance: keeps asking for more time to feel satisfied.
• 5. Secret use: uses the device when they think no one is watching.
• 6. Lying about usage: says they stopped but keeps going.
• 7. Sleep problems: trouble falling asleep, restless sleep.
• 8. Declining school performance: trouble focusing, falling grades.
• 9. Social withdrawal: prefers the screen to friends.
• 10. General irritability: edgy and restless away from the screen.
