This study aims to enhance our knowledge of the associations between the quality of the language-learning environment in toddler childcare groups and children's vocabulary development from age 3 to age 5. Participants were 1,131 children (48% girls; age at T1 assessment: M = 35.5 months, SD = 2.7; age at T2 assessment: M = 60.3 months, SD = 1.4)…

The Sustainable Development Goals mandate that by 2030, all children should have access to quality early child development opportunities, healthcare and pre-primary education.

Children's…

This study used a British cohort ("n" = [approximately]13,000) to investigate the association between child care during infancy and later cognition while controlling for social selection and missing data. It was found that attending child care (informal or center based) at 9 months was positively associated with cognitive outcomes at age…
