Children’s health care is an important discipline that promotes children’s growth and development, maintains children’s health and ensures their quality of life. Infants and young children are in the process of continuous growth and development, and their diet, nutrition, psychology, and behavior are closely related to their health in adulthood. However, parents have little knowledge of child health care, and health care knowledge on the Internet is a mixed bag, so it is not advisable for parents to blindly follow it. Children’s health care professionals provide advanced nutrition and feeding knowledge, early screening and treatment of nutrition-related diseases; monitor children’s growth and development, and provide scientific treatment and follow-up guidance for children with growth deviations; provide knowledge of early childhood education for all ages; find and correct bad habits, and cultivate and set up a healthy behavior, so as to take care of children’s physical and mental health and growth in all aspects!
