An infant is a term used to describe a child in the early stages of life, typically from birth up to one year of age. Infancy is a crucial developmental period, during which a child undergoes rapid growth and development in all aspects, including physical, cognitive, and social-emotional development. Infants require a great deal of care and attention, including feeding, bathing, and diapering. They also need plenty of rest and stimulation to promote their development. Infants develop at their own pace and may reach developmental milestones, such as sitting up, crawling, and walking, at different times. It is important for parents and caregivers to provide a safe and nurturing environment for infants to promote their growth and development. Healthcare professionals also play a crucial role in monitoring and promoting the health and development of infants through regular checkups and vaccinations.
