Neonates are newborns, specifically infants who are less than 28 days old. This stage of life is crucial for development, as neonates undergo significant physical and physiological changes. They rely entirely on caregivers for nutrition, warmth, and protection, typically feeding on breast milk or formula. During this period, neonates are assessed for health issues and developmental milestones. Common assessments include checking their weight, reflexes, and overall responsiveness. Proper care during the neonatal stage is essential for ensuring a healthy transition to infancy and childhood, laying the foundation for future growth and development.
