What is infant definition?

Infant refers to a child who is in the earliest stage of life, typically from birth up to around 12 months of age. This stage is also known as the newborn or baby stage. Infants are completely dependent on caregivers for all aspects of their survival and development. They require constant attention and care to maintain their health, safety, and wellbeing. During this stage, infants experience rapid physical, cognitive, and emotional growth as they develop new skills and abilities. Infants are vulnerable to a range of health issues and require regular check-ups to monitor their growth and development.
