Instead of using the same bottle all the time, there should be a number, so that there will be plenty of time to clean them. If three feeds are given each day, there should be six bottles. If four feeds are given, eight bottles. Use a set every other day. The bottles should be rinsed out after being used. Then boil them in water containing soda or a little lye, rinse in several waters and set them aside. If it is sunny, let them stand in the sun. Before using, rinse again in sterile water. The nipples should have equally good care. In feeding babies cleanliness comes before godliness.

Each bottle is to be used for but one feeding, and as many bottles are to be prepared as there are to be feedings for the day.

If the people live in the country it is easy to get pure milk. If in the city one should make arrangements with a reliable milk man possessed of a conscience. It is well to get the milk from a certain cow, instead of taking a mixture coming from many cows. Select a healthy animal that does not give very rich milk, such as the Holstein. She should have what green food she wants every day, grass in summer, and hay of the best quality and silage in winter. The grain ration should be moderate, for cows that are forced undergo quick degeneration. They are burned out. The cow should not be worried or whipped. She should be allowed to be happy, and animals are happy if they are treated properly. The water supply should be clean, not from one of the filthy tubs or troughs which disgrace some farms. The barn should be light and well ventilated. It should be kept clean and free from the ammonia fumes which are found in filthy stables. The cow should be brushed and the udder washed before each milking. The milker should wash his hands and have on clothes from which no impurities will fall. The first part of the milk drawn should not be put in with that which is to supply the baby. The milk should be drawn into a clean receptacle and immediately strained through sterile surgeon's cotton into glass bottles. These are to be put aside to cool, the contents not exposed to the dust falling from the air. Or the milk may be put directly into the nursing bottles and put aside in a cold place until needed. Then warm milk to 100 degrees Fahrenheit.

Pardon a little repetition: If possible let the child nurse. If there is not enough milk, let the baby take what there is and give cow's milk in addition. If it is impossible to feed the baby at the breast, get the milk from a healthy cow that is kept clean, well fed and well treated. The cow's milk should be prepared as follows: Take equal parts of milk and water. Or take two parts of milk and one part of water. Mix, and to this may be added sugar of milk in the proportion of one level teaspoonful to the quart. Before feeding raise the temperature of the milk to about 104 degrees Fahrenheit, so that it will be about 100 degrees when fed. It is best to do the warming in a water bath.

Milk should not be kept long before being used. Limit the age to thirty-six hours after being drawn from the cow. Twenty-four hours would be better. The evening milk can safely be given to the infant the next day, if proper precautions have been taken. Ordinary milk is quite filthy and upon this babies do not thrive. Make an effort to get clean milk for the baby.

The composition of human milk and cow's milk is about as follows:

  ====================================================================
               Water     Albumin     Fat     Sugar     Salts
  --------------------------------------------------------------------
  Human .....  87.58        2.01    3.74      6.37       .30
  Cow's .....  87.27        3.39    3.68      4.97       .72
  --------------------------------------------------------------------

The albumin in human milk is largely of a kind which is not coagulated by souring, while nearly all the albumin in cow's milk coagulates. The uncoagulated albumin is digested and taken up more easily by the baby's nutritive system than that which is coagulated. This is one of the reasons that babies do not thrive so well on cow's milk as on their natural food.

The sugar of milk is not like refined sugar. Although it is not so easily dissolved in water, and therefore does not taste as sweet as refined sugar, it is better for the child. If sugar is added to the milk, milk sugar should be used. The druggists have it in powder form.

The addition of barley water and lime to the baby's milk is folly. The various forms of modified milk do not give as good results as the addition of water and a little milk sugar, as previously described. If you believe in such modifications as the top milk method and the addition of starchy substances and lime water, I refer you to your family physician or text-books on infant feeding.

It is difficult to improve on good cow's milk. It is well to remember that the human organism is very adaptable, even in infancy. The principal factors in infant feeding are cleanliness and moderation.

Bottle-fed babies should be given fruit or vegetable juices, or both, very early and it would be well to give a little of these juices to breast-fed babies too. The latter do not require as much as the former. Begin during the first month with a teaspoonful of orange juice put into the drinking bottle once a day. Increase gradually until at four or five months the amount may be from one to two tablespoonfuls. Do not be afraid to give the orange juice because it is acid, for it splits up quickly in the stomach and is rearranged, forming alkaline salts. It is the fruit that can be obtained at nearly all seasons. It is best to get mild oranges and strain the juice. The fruit is to be in prime condition. Instead of orange juice, the juice of raw celery, spinach, cabbage, apples, blackberries and other juicy fruits and vegetables may be employed, but these juices must all come from fruits or vegetables that are in prime condition. No sugar is to be added to either the fruit or the vegetable juices.

The mother's milk coagulates in small flakes, easily acted upon by the digestive juices, after which they are readily absorbed. Cow's milk coagulates into rather large pieces of albumin which are tough and therefore rather difficult to digest. This happens when the milk is taken rapidly and undiluted. However, when diluted and taken slowly this tendency is overcome to a great degree. For this reason it is best to get nipples with small perforations.

Either pasteurization or sterilization of milk is almost universally recommended by medical men. Even those who do not believe in such procedures generally fail to condemn them without qualifying statements. For a discussion of this fallacy I refer you to the chapter on milk.

Do not give the little ones any kinds of medicines. They always do harm and never any good. If any exception is made to this, it is in the line of laxatives or mild cathartics, such as small doses of castor oil, cascara segrada or mineral waters, but there is no excuse for giving metallic remedies, such as calomel. If the babies are fed in moderation on good foods they will not become constipated. If they are imprudently handled and become constipated it is necessary to resort to either the enema or some mild cathartic. Bear in mind that such remedies do not cure. They only relieve. The cure will come when the errors of life are corrected so that the body is able to perform its work without being obstructed.
