To promote appropriate toddlers' behaviours at age 18 months, elevated background TV exposure over time should be discouraged. Furthermore, paediatricians should emphasise such effects of TV exposure on child behaviours with parents at health supervision visits. As such, parents will be aware of the detrimental effect of increased background TV exposure over time on their children's behaviours.

Infants exposed to screen media in the evening at 12 months of age had decreased 12-month night-time sleep duration. To promote good sleep hygiene and optimal sleep for infants at this age, screen media exposure after 7 pm should be avoided.
