Interest in the study of children and awareness of the value of educating their parents in wholesome child-rearing practices began to grow around the beginning of the 20th century.

This began abroad, where such leaders as Maria Montessori and the McMillan sisters pioneered child care as a means of improving the well-being of children of the poor.
