Child development researcher, Lian Tong, analysed the results from a Haley and Stansbury experiment saying, "Parent responsiveness also facilitates cognitive, social, and emotional development and reduces negative emotions in infants."[31] That is, the amount of time that a parent or teacher is willing to spend teaching, listening to, playing with, and exploring with the child the more socially, emotionally, and educationally developed the child will become. Whether that child receives the majority of his or her care at a center or at its house, the biggest factor in deciding what will have the best effect on the child will be those willing to put in the time and effort it takes to properly develop a child's social, physical, and academic skills.

The first crèche was opened by Firmin Marbeau on 14 November 1844 in Paris,[62] The Société des Crèches was recognized by the French government in 1869. Originating in Europe in the late 18th and early 19th century, day cares were established in the United States by private charities in the 1850s, such as the Charity Organization Society founded by Ansley Wilcox. The Fitch Creche in Buffalo, New York was known as the first day center for working mothers in the United States. Another at that time was the New York Day Nursery in 1854.
