Through Child development

Locomotion

One of the Adolph's most heavily studied subjects is Locomotion. She considers it to be the biggest achievement for an infant. In her articles she explains which phases of movement lead to higher accomplishments. For example, “Tripod” sitting is followed by sitting without any need for hands to balance. Babies crawling scooting around on their stomach gives way for them to start crawling around on hands and knees. Infants generally crawl around 9 months of age. After learning to crawl, babies transition to walking around 18 months. This alters infants' vantage points and gives them new perspectives inside their environment.

Locomotion comes along rapidly just like a child's growth, but everything is very gradual and in baby steps. It is important to know all individuals develop differently, and milestones are based on averages. Adolph presents an important part of this developmental stage, which is “learning to learn.” She says, “The notion of learning to learn provides a framework for understanding how ongoing actions are adapted to cope with variability and novelty.” Adolph discusses how locomotion also encourages infants to explore their environment more and experience challenges such as stair climbing, avoiding dangerous surfaces, and testing the limits of their surroundings. Low impact errors, such as a slight stumble or fall, allow children to continue practicing to crawl, walk, and explore. Adolph and Han found infants are not dissuaded by these many mistakes when learning new developmental skills.
