A recent Journal of the American Medical Association (JAMA) study article found screen time in young children was significantly related to mental health problems.

 "Conclusions and relevance Results of this study indicated that both total screen time and different types of content were associated with mental health problems in children aged 3 to 6 years. Limiting children’s screen time, prioritizing educational programs, and avoiding non–child-directed programs are recommended." Source: JAMA 

 The American Academy of Child and Adoscent Psychiatry has provided some tips in 2020: " Managing a child’s screen time is challenging for families. Your child is never too young for a screen-time plan. Consider the following as a guideline:

• Until 18 months of age limit screen use to video chatting along with an adult (for example, with a parent who is out of town).
• Between 18 and 24 months screen time should be limited to watching educational programming with a caregiver.
• For children 2-5, limit non-educational screen time to about 1 hour per weekday and 3 hours on the weekend days.
• For ages 6 and older, encourage healthy habits and limit activities that include screens.
• Turn off all screens during family meals and outings.
• Learn about and use parental controls.
• Avoid using screens as pacifiers, babysitters, or to stop tantrums.
• Turn off screens and remove them from bedrooms 30-60 minutes before bedtime. "
