A Stanford and Berkeley study of over 14,000 children finds pre-school/daycare harms social development.
“The UC Berkeley-Stanford study found that all children who attended preschool at least 15 hours a week displayed more negative social behaviors such as trouble cooperating or acting up, when compared with their peers. The discrepancies were most pronounced among children from higher-income families.”
Note: No research has demonstrated that “moderate” advantage in cognitive tests for children in “high quality” preschool/daycare endure in the long term.
Note: The majority of daycares in the US and Canada have been found to be of low quality.
