How old is kid. The appetite parameters and sleep habits of kids vary with age and stage of growth. The rapid growth rate of the first yr slows to 1/3 as fast by 2, picking up again by puberty. Appetite reflects growth rate & state of health. Sleep habits follow a variety of influences, mostly anxiety-separation issues in toddlers. Clearly stating a kids age/stage will permit for focused answers.
