Baby vs. Child: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on January 5, 2024
A baby is a very young human, typically under two years, while a child refers to a young person from infancy to puberty.

Key Differences

A baby is typically considered to be from birth to around 2 years old, a time marked by rapid physical and cognitive development. A child, in a broader sense, includes this baby stage but extends to the onset of puberty, encompassing a wider range of developmental stages.
Babies are highly dependent on adults for all their needs, including feeding and mobility. Children, as they grow, develop greater independence, acquiring skills like walking, talking, and self-feeding.
Social and emotional development in babies involves basic interactions, like smiling and recognizing close individuals. As children, these interactions become more complex, including forming friendships and understanding emotions.
Babies communicate primarily through crying and basic sounds, gradually learning words. Children develop more complex language skills, engaging in conversations and expressing detailed thoughts.
Physical growth in babies is rapid, with milestones like sitting and crawling. Children experience a more varied physical development, engaging in diverse activities like running, playing sports, and artistic pursuits.
