After that, it enters the relatively slower preschool and school age periods, and the growth and development speed slows down and tends to be stable, with an average increase of about 5 centimeters per year. During this period, children's basal metabolic rate is higher, and anabolism in the body is greater than catabolism. It is also necessary to provide sufficient energy and nutrients.
