The establishment and maintenance of satisfactory feeding is one of the basic concerns of those involved in caring for the infant. At first the baby's progress is measured in terms of his weight gain and growth, how well he takes his food and how contented he is. A little later, we anticipate his first smile, a growing awareness of his world, reaching and moving to explore and respond to it. Such new experiences as orange juice, cereal from a spoon, getting his first tooth, getting hands into his mouth, sucking his fingers, sitting up, babbling, eating strained foods, chewy foods — all mark milestones in the first year of life. When he is sick he goes “off his food”. His well-being and progress are reflected in the feeding situation.
