Discuss the changes that take place when an infant becomes a toddler.

Answers will vary. Toddlers run about, supporting their relatively heavy heads and torsos by spreading their legs in a bowlegged fashion. Because they are top-heavy and inexperienced, they fall frequently. Many toddlers are skillful at navigating slopes. They walk down shallow slopes but prudently choose to slide or crawl down steep ones. Walking lends children new freedom. It allows them to get about rapidly and to grasp objects that were formerly out of reach. Give toddlers a large ball to toss and run after; it is an inexpensive and most enjoyable toy. As children mature, their muscle strength, bone density, and balance and coordination improve. By the age of two years, they can climb steps one at a time, placing both feet on each step. They can run well, walk backward, kick a large ball, and jump several inches.
