0-3 years refers to the period from a child's birth to their third birthday, totaling 36 months. This period includes three stages: the neonatal period (from birth to 28 days), the infant period (from the end of the neonatal period to one year of age), and the preschool period (from one year of age to three years of age). Before the neonatal period, the child has been safely and comfortably sleeping in the mother's warm, secure, and cozy uterus, growing happily with the nutrition and oxygen supplied by the mother. From the time the umbilical cord is tied at birth, the direct connection between the child and the mother is severed, marking the beginning of the neonatal period and the start of a relatively independent life. They must learn to breathe independently to obtain oxygen, eat independently to gain nutrition, and adapt to the external environment. The neonatal period is the period with the highest infant mortality rate and also the period that requires the most adult help, care, and love.
After the neonatal period and up to one year of age is the infant period. By this stage, the child has already survived the initial four weeks after birth. They can now breathe freely, nurse, sleep, and play. Gradually, they begin to recognize and love their parents and grandparents, learning to communicate with them. The baby is no longer lying down all day and gradually learns to lift their head, stand straight, sit up, crawl, stand, and walk, mastering the basic movements and skills necessary for life. They are also becoming smarter and more understanding, able to think, express their joys, sorrows, anger, and happiness; play with toys, use tools; and communicate ideas with family and friends. During this period, children grow and develop rapidly, becoming healthier and smarter; however, they are still prone to nutritional issues and are vulnerable to diseases, accidents, and other injuries.
