Document Summary
Chapter 9: physical development & health in early childhood. Abdominal muscles develop & toddler potbelly tightens. Body proportions become more adult-like (head still relatively large though) Boys are slightly taller, heavier & have more muscle per kg then girls (who have more fatty tissue) Cartilage turns to bone at a faster rate. Bone becomes harder: firmer shape & protection of organs. Development of motor skills: coordinated by maturing brain & nervous system. Increased physical stamina: b/c increased capacities of respiratory & circulatory system. Proper growth & health depend on good nutritional & adequate sleep. Likely to become overweight if not active. Beginning at age 2 healthy diet is same as adults: fruits & veggies, whole grains, low-fat & non fat dairy products, beans, fish, & lean meats. Preschoolers eat less in proportion to their size than infants do: as growth slows need fewer calories. Children who self-regulate their feeding are more likely to consume the proper # of calories.
