The critical period for speech and language development is early
The impact of screen use on a child’s communication development is a significant concern. The critical time window for the development of speech, language, and social skills is between birth and 3 years. What happens then is the precursor for later reading and writing skills that are key to academic and vocational success.
A meta-analysis published in JAMA Pediatrics in July 2020 found that greater quantity of screen use was associated with poorer language skills – while screen-use onset at later ages was also associated with stronger child language skills. A November 2019 JAMA Pediatrics study using brain imaging in pre–school age children found an association between increased screen-based media use, compared with the AAP guidelines, and lower integrity of white matter tracts supporting language and emergent literacy skills. That study also used several language and literacy tests, finding that children with higher screen exposure had poorer expressive language and worse language processing speed. A 2017 study of 900 children between 18 and 24 months found that every 30-minute increase in daily screen time was linked to a 49% increased risk of expressive speech delay. And on the parental side, numerous studies have documented decreased verbal and nonverbal interactions initiated by parents when they are using a device.
Be tech wise with baby
AAP offers many resources in its Media and Children Communication Toolkit that serve as helpful starting points for conversations, including its family media use plan templates. However, more resources tailored to parents of newborns and very young children are needed.
One new option recently developed by the American Speech-Language-Hearing Association (ASHA) and the Children’s Screen Time Action Network is Be Tech Wise With Baby! Aimed at prospective and new parents, this simple handout, available for free in English and Spanish, is an easy takeaway from early well-child visits that pediatricians and pediatric nurses can distribute.
Pediatricians have a vital role to play championing healthy, balanced screen time use for children and adults – starting from baby’s first moments of life. By guiding new parents towards simple steps, such as carving out tech-free times of day and delaying introduction of screens, they can positively influence the screen-time habits of the next generation of connected kids.
