Newborn care involves comprehensive medical attention and nurturing practices to ensure an infant's optimal health, growth, and development. It includes proper nutrition through breastfeeding or formula feeding, maintaining hygiene to prevent infections, and monitoring vital signs such as temperature, weight, and hydration. Regular medical check-ups, vaccinations, and screenings help detect and prevent potential health issues early. Additionally, newborn care focuses on safe sleeping practices, umbilical cord care, and skin care to promote overall well-being.
