Infant vs. Child: What's the Difference?
By Janet White || Published on December 12, 2023
"An infant typically refers to a very young baby, especially from birth to one year old, while a child denotes a young person, usually between infancy and adolescence."
Key Differences
An infant is a term used for a very young baby, often considered to be from birth to 12 months. A child, in contrast, refers to a young person from the toddler stage up to puberty.
The developmental stages of an infant include rapid physical growth and beginning milestones in mobility and speech. In comparison, a child continues to grow and develop more complex skills in these areas.
Nutritionally, infants primarily rely on milk, including breast milk or formula. Children, however, have a more diverse diet, gradually including a variety of solid foods.
In terms of care, infants require constant supervision and assistance in all activities. Children gain increasing independence, learning to perform basic tasks on their own.
Legally and socially, the term infant can be used to define a child under a certain age, often under one year. The term child can encompass a broader age range, often until the age of 18.
