The American Academy of Pediatrics defines early childhood as the ages between one and five years, encompassing the toddler and pre-school periods. Early childhood development occurs rapidly and is widely recognized as extremely important in setting the foundation for future learning, including the social, cognitive, and motor skills needed to handle the demands of pre-school and kindergarten.
