This document discusses the key characteristics and developmental milestones of babyhood. It covers six main areas: motor development, speech development, understanding, emotional development, socialization, and moral development. Motor development progresses from head to toe and from the center of the body outward. Important motor milestones include rolling over, sitting up, crawling, cruising, pulling to stand, walking while holding on, and walking independently. Speech development starts with crying and cooing before advancing to babbling and first words. Social and emotional development involve forming attachments to caregivers and learning to interact with others. Moral development occurs as babies learn rules and codes of behavior from parents and peers.
