Frequently Asked Questions
Q
What are the AAP screen time guidelines by age?
The American Academy of Pediatrics recommends no screen time for children under 2 (except video calls), up to 1 hour/day of high-quality content for ages 2-5, and consistent limits for ages 6+. For teens and adults, limit recreational screen time to 2 hours/day maximum.
Under 18 months: No screens except video calls
18-24 months: Only with parent, high-quality content
2-5 years: Max 1 hour/day of educational programming
6-12 years: Consistent limits, prioritize sleep and physical activity

Q
How much screen time is too much for kids?
Children averaging more than 2 hours/day of recreational screen time show increased risk of attention problems, sleep disruption, and reduced physical activity. The average US child gets 4-6 hours of screen time daily, which is 2-3x the recommended limit. Over a year, that excess adds up to 730-1,460 hours.
Average US child: 4-6 hours/day of screen time
AAP recommended: 1-2 hours/day (age-dependent)
Excess of 2+ hours linked to attention problems
Screen time before bed disrupts sleep by 30-60 minutes
Every hour over the limit = 365 hours/year lost to screens

Q
Does educational screen time count toward the limit?
The AAP does not fully exempt educational content from limits. For ages 2-5, educational programs like PBS Kids count toward the 1-hour limit. For older children, required school or homework screen use is separate from recreational limits, but voluntary educational apps still count toward the 2-hour guideline.
Ages 2-5: All screen time counts toward 1-hour limit
School homework: Generally excluded from recreational limits
E-reading: Moderate amounts are acceptable with breaks
Q
How does screen time affect sleep?
Screen use within 1 hour of bedtime delays sleep onset by 30-60 minutes due to blue light suppressing melatonin production. Children who use screens in the bedroom get 20-30 minutes less sleep per night, totaling 2-3.5 hours less sleep per week. The AAP recommends screen-free bedrooms and a 1-hour screen curfew before bed.
Blue light suppresses melatonin production
Delays sleep onset by 30-60 minutes
Bedroom screens reduce sleep by 20-30 min/night
Weekly sleep loss: 2-3.5 hours from bedroom screens
Screen curfew: Stop all screens 1 hour before bedtime
Use night mode/blue light filters in the evening
Q
What are healthy alternatives to screen time?
Replace screen time with physical activity (60 min/day recommended), creative play, reading, outdoor time, board games, arts and crafts, or family conversations. Children who spend 1+ hour outdoors daily have 50% lower rates of nearsightedness and better sleep quality.
Physical activity: 60 minutes/day for children
Outdoor play: Reduces nearsightedness risk by 50%
Reading physical books: Improves focus and vocabulary
Creative play: Building, drawing, imaginative games
Family time: Board games, cooking together, conversations
