EXCERPT

> Question: Is there a dose-response association between screen time for children aged 1 year and functional development at ages 2 and 4 years?
>
> Findings: In this cohort study including 7097 mother-child pairs, a dose-response association was observed between greater screen time at age 1 year and developmental delays in communication and problem-solving at ages 2 and 4 years.
>
> Meaning: These findings suggest that domains of developmental delay should be considered separately in future discussions on screen time and child development.
