According to the 24-Hour Movement Guidelines, teens should only get two hours of recreational screen time a day.
On average, children ages 8-12 in the United States spend 4-6 hours a day watching or using screens, and teens spend up to 9 hours.
For 8-10 years olds, the recommended amount is six hours,
For 11-14 years olds it is nine hours, and for 15-18 years olds it is seven and 1/2 hours.
The American Academy of Pediatrics discourages media use by children younger than 2 and recommends limiting older children's screen time to appropriate amounts.
If introducing digital media to children ages 18 to 24 months, make sure it's high quality and avoid solo media use. For children ages 2 to 5, limit screen time to one hour per day of high-quality programming.
