WEIGHT, GROWTH, AND DEVELOPMENT

Оглавление

Of what importance is the weight of the child?

Nothing else tells so accurately how well it is thriving.

During the first year a record of the weight is almost indispensable; throughout childhood it is of much interest and is the best guide to the physical condition. It will well repay any mother or nurse to keep such a record.

How frequently should a child be weighed?

Every week during the first six months, and at least once in two weeks during the last six months of the first year. During the second year a child should be weighed at least once a month.

How rapidly should an infant gain in weight during the first year?

There is usually a loss during the first week of from four to eight ounces; after this a healthy child should gain from four to eight ounces a week up to about the sixth month. From six to twelve months the gain is less, usually from two to four ounces a week.

Is it to be expected that bottle-fed infants will gain as rapidly as those who are nursed?

They seldom do so during the first month; after that time under favourable circumstances the gain is usually quite as regular, and during the latter half of the first year it is likely to be more continuous than in a nursing infant, because the latter usually loses weight at the time of weaning.

Why do they not gain so rapidly at first?

It takes a few weeks for the stomach to become accustomed to cow's milk, and until this is accomplished it is necessary to make the milk very weak or the child's digestion will be upset.

For a child of average weight at birth (seven to seven and a half pounds) what should be the weight at the different periods during the first year?

At three months it should be twelve to thirteen pounds; at six months, fifteen to sixteen pounds; at nine months, seventeen to eighteen pounds; at one year, twenty to twenty-two pounds. At five months a healthy child will usually double its weight, and at twelve months it will nearly treble its weight.

Do all healthy infants gain steadily in weight during the first year?

As a rule they do; yet it is seldom the case that one gains every week for the entire year. With most infants there are from time to time periods of a few weeks in which no gain is made. These are more often seen from the seventh to the tenth month and frequently occur when the child is cutting teeth, sometimes during very hot weather.

Is it true that every infant who gains rapidly in weight is thriving normally?

Not invariably. Some who are fed upon prepared infant foods increase rapidly in weight but not in strength, nor in their development in other respects.

Is the weight of as much value in the second year as a guide to the child's condition?

After the first year, the gain in weight is seldom continuous; there are many interruptions, some depend on season, and others often occur without apparent cause.

At what age should the fontanel close?

The average is about eighteen months. It seldom closes earlier than fourteen months, and it should not be open at two years.

At what age should a child hold up its head?

As a rule during the fourth month, and often during the third month, the head can be held erect when the body is supported.

When does an infant first laugh aloud?

Usually from the third to the fifth month.

When does it begin to reach for toys and handle them?

Usually from the fifth to the seventh month.

At what age should a child be able to sit and to stand alone?

At seven or eight months a healthy child is usually able to sit erect and support the body. During the ninth and tenth months are usually seen the first attempts to bear the weight upon the feet, and at eleven or twelve months most children can stand with assistance.

When should a child walk alone?

The first attempts are generally seen in the twelfth or thirteenth month. At fifteen or sixteen months the average child is able to run alone.

What conditions postpone these events?

Prematurity, a very delicate constitution, any severe or prolonged illness, and especially chronic disturbances of digestion making feeding difficult. A common cause of late sitting, standing, or walking is rickets.

Should a child be urged to walk?

Never; he is usually quite willing to do so as soon as his muscles and bones are strong enough. None of the contrivances for teaching children to walk are to be advised.

When do children begin to talk?

Generally at one year a child can say "papa" and "mamma" or other single words. At the end of the second year the average child is able to put words together in short sentences.

If at two years the child makes no attempt to speak, what should be suspected?

Either that the child is a deaf-mute or that it is mentally deficient, although this is occasionally seen in children who are only very backward.
