Childcare : what the science says

The article reviews research on childcare, arguing that its effects depend on a child’s age, hours in care, and family environment. It highlights research associating long hours of daycare at younger ages with later behavioral difficulties and poorer social skills, while noting differences by socioeconomic status.

This article seems to suggest that starting daycare later (after 2.5) is better. Also potentially more pronounced benefits of daycare for lower socio-economic status families/households. Would love to understand whether this evidence suggested in this article is reflective of the larger literature and people's thoughts in general.
