18 months: human growth follows the cephalocaudal principle, toddlers have a disproportionately large head and trunk. As growth of hips, legs, feet catches up, children"s bodies take on: virtually all the body"s muscle fibres are present at birth more adult proportions, during childhood, muscles become longer and thicker as individual fibres fuse together. Happens gradually at first, then more rapidly during adolescence: more pronounced in girls, up to age of 2, children at high-risk for adult obesity. Based on family factors, tend not to differ in terms of body mass from children at low risk for adult obesity. Variations on the average profile: secular growth trends changes in physical development from one generation to the next, quite large in industrialized nations, what is normal can vary greatly, applies to all aspects of development. Most adults have normal proportions, but quite short. 5. 5 kg 3-month-old should eat about 110 calories/kg of body weight or 600 calories.
