(AJC) — How much TV is too much TV for babies and toddlers? A new study out of Canada will increase the debate about the question.

The study found that every hourly increase in daily television viewing at 29 months of age is associated with diminished vocabulary and math skills, classroom engagement (which is largely determined by attention skills), victimization by classmates, and physical prowess at kindergarten, according to Linda Pagani of the University of Montreal and the CHU Sainte-Justine children’s hospital.

Pagani is professor of Psycho-Education and Researcher in Brain Diseases at the Sainte-Justine Hospital Research Center. Her area of expertise is child development, particularly in the area of school readiness and socio-emotional development in children.
