Help doctors understand the growth and development of young children, provide basis for diagnosis and treatment, and help parents better understand and pay attention to the health status of young children. Establish a health information package to provide accurate information for future disease diagnosis and help doctors diagnose and choose reasonable drugs. It helps to protect children's health and promote their all-round development.
