A study in JAMA Pediatrics found a relationship between screen time as a baby and developmental delays as a toddler. This draws more ground to further investigate the health effects of electronics usage by children and what types of media have detrimental effects on development.

Substantial confounding in studies like this though. I haven’t read the paper but they usually can only control for basic demographics, not the nuances of parenting style and engagement, which could certainly be correlated with both screen time and development.
