Answer to Question 2ANSWER: (1) stability, (2) locomotion, and (3) manipulation. At around six weeks, infants begin to hold their heads steady and erect. By two months, they lift their upper bodies by their arms and can roll from side to back. From three to four months, babies begin grasping palm-size objects and can roll from back to side. From six to eight months, they can sit alone and begin to crawl. Between eight and ten months, babies pull up to stand and perhaps play patty cake. At this time they begin to stand alone, and then begin to walk. From 13 to 16 months, children can build a tower of two cubes, vigorously scribble with a large crayon, and begin to walk up stairs with help. At around 20 to 24 months, toddlers begin to jump in place and kick objects. By 26 to 30 months, children begin to climb, stand on one foot, and have some interest in toilet learning. Usually at around 36 months, the child can jump and independently use the toilet.
