This is a three-part series. In A Whole New World, sensory motor development from birth to 1 year is described. In The Language of Being, language acquisition, the use of tools and hand-eye coordination is described. In Reason and Relationships, focusing on ages 2 - 3, the development of thinking, how babies relate to people, form attachments, and develop a sense of self are illustrated. The video does not offer practical advice or information about basic infant care or toddler discipline.
