Infant vs. Juvenile — What's the Difference?

An infant refers to a very young child, usually under one year old. Infants are highly dependent on their caregivers for all their needs and are in the earliest stages of development. They rely on others for feeding, movement, and protection, showing rapid growth and developmental changes. A juvenile, on the other hand, is an older child or adolescent, typically between the ages of 10 and 18. Juveniles have gained a significant level of independence compared to infants. They are more self-sufficient, capable of performing daily activities without constant supervision, and are in the midst of developing social, cognitive, and emotional skills.

Infants communicate primarily through crying and basic sounds, indicating their needs and emotions indirectly. Their understanding of language and ability to interact is just beginning to form. Whereas juveniles have developed more advanced communication skills, including speaking, reading, and writing, enabling them to express themselves clearly and engage in complex social interactions.

Infants' primary focus is on basic survival and initial learning through sensory experiences. They are beginning to understand the world around them through touch, sight, and sound. In contrast, juveniles are focused on more complex learning, including formal education and developing personal interests, as well as understanding abstract concepts and critical thinking.
