Crawling is a form of movement where an individual moves on their hands and knees or by dragging their body along the ground. This method is commonly seen in infants as they develop motor skills and gain strength. Crawling helps them explore their environment and build coordination. In addition to infants, many animals, such as cats and dogs, also crawl as a natural way to move. Crawling can be useful in various situations, such as when a person needs to move quietly or navigate through tight spaces, like in military operations or obstacle courses.
