What term refers to an infant's ability to move from one place to another?

The term "locomotion" specifically describes the ability of an infant to move from one place to another, which can include rolling, crawling, walking, or any other form of self-initiated movement. This ability typically develops progressively as infants gain strength, coordination, and an understanding of their environment. Locomotion is a significant milestone in an infant's development, as it opens up opportunities for exploration and interaction with the surrounding world, fostering cognitive, social, and emotional growth.

The other terms, while related to movement, do not specifically denote the act of moving from one place to another. "Manipulation" often refers to the ability to move and handle objects with one's hands, which is important for fine motor skills. "Mobility" is a broader term that encompasses the capability to move but does not pinpoint the action of moving from one location to another. "Movement" is also a general term that refers to any change in position of the body or its parts, lacking the specificity that "locomotion" provides in the context of self-propulsion.
