Longitudinal associations between maternal and child screen use at 1 year of age and child behavior and development at 3 years of age

Young children are increasingly exposed to evolving screen technology. International guidelines recommend no screen use for children under the age of 2 years, due to the potential for detrimental effects on behaviour and development. However, evidence for these guidelines is limited by inadequate consideration of device-specific effects (TV and mobile phone/tablet computer), maternal screen use, confounders such as maternal mental health and importance of effect sizes.
