Pediatrics is a branch of medicine that focuses on the health and medical care of infants, children, and adolescents, typically from birth up to 18 years of age. It is a specialized field that deals with the physical, emotional, and social well-being of young patients, as well as their growth and development.

Pediatricians are medical doctors who specialize in pediatrics. They undergo additional training after medical school to acquire the knowledge and skills necessary to diagnose, treat, and prevent illnesses in children. Pediatricians provide a wide range of healthcare services, including routine check-ups, vaccinations, treatment of common illnesses and injuries, management of chronic conditions, and guidance on nutrition, behavior, and development.

Pediatrics covers various sub-specialties such as neonatology (care of newborn infants), pediatric cardiology (heart conditions in children), pediatric oncology (cancer in children), pediatric gastroenterology (digestive system disorders), and many others. The field of pediatrics is essential for ensuring the health and well-being of children as they grow and develop into adulthood.
