Children's House began as a non-profit, volunteer, parent-run school in September 1965 in classrooms at the original Fairless Hills Methodist Church (currently the Children's House building). At that time there were two directresses, two assistants, and a student body of fifty-one children in two classes.
As the reputation of the school grew, the increased enrollment and long waiting list required the addition of another classroom. By 1980, there were three morning classes, two afternoon classes and a kindergarten program. The staff consisted of four American Montessori Internationale affiliated directresses and five aides.
Responding to a growing waiting list, the school added a modular classroom for the Fall 1997. The school is licensed for a maximum enrollment of 85 students in the pre-primary program, two morning primary classes, and a full day primary program, and a kindergarten program.
