The American Academy of Pediatrics (AAP) recommends that parents and caregivers minimize or eliminate altogether media exposure for children under the age of two.
For older preschool-aged children, media limits are very appropriate, and parents should have a strategy for managing electronic media when choosing to maximize its benefits.
Remember that supervised independent play for infants and young children has been shown to have superior benefit to the use of screen media when you cannot sit down and actively engage in play with your child. For example, have your child play with nesting cups on the floor nearby while you prepare dinner.
Also, avoid placing a television set in your child's bedroom and recognize that your own media use can have a negative effect on children.
