The following is the mode of preparing the milk: Allow one-third of a pint of new milk to stand for about twelve hours, remove the cream and add to it two-thirds of a pint of new milk, as fresh from the cow as possible. Into the one-third of a pint of blue milk left after the abstraction of the cream, put a piece of rennet about one inch square. Set the vessel in warm water, until the milk is fully curdled, an operation requiring from five to fifteen minutes, according to the activity of the rennet, which should be removed as soon as the curdling commences, and put into an egg cup for use on subsequent occasions, as it may be employed daily for a month or two. Break up the curd repeatedly, and carefully separate the whole of the whey, which should then be rapidly heated to boiling in a small tin pan placed over a spirit or gas lamp. During the heating a further quantity of casein, technically called ‘fleetings,’ separates, and must be removed by straining through muslin. Now dissolve 110 grains of powdered sugar of milk in the hot whey, and mix it with the two-thirds of a pint of new milk, to which the cream from the other third of a pint was added, as already described. The artificial milk should be used within twelve hours of its preparation, and it is almost needless to add that all the vessels employed in its manufacture and administration should be kept scrupulously clean. Any babe can be fed from the first with a spoon, and in a few weeks it will drink from a cup or glass. When it seems necessary to use the nursing bottle the utmost care should be taken to keep it clean and sweet. Two bottles should be used alternately. The one not in use should be thoroughly rinsed, and then laid (without the nipple) in an earthen or granite dish, containing a solution of common soda. Let it remain there until needed, then rinse it well, and you may feel that it is in good condition. Cleanse the nipple by hand. Do not use the rubber tube. A young babe should not be fed more frequently than once in two hours, and by the time it is three months old once in three hours is preferable. Most children, when four or five months old, can be taught to sleep all night without nursing. Nothing deranges a child’s digestion more than irregular and constant nursing. I have seen a mother give her child the breast five times during a half-hour’s conversation. It is unreasonable to suppose that a child is hungry every time it nestles and frets. Consider the time since it has nursed, and look for other causes of uneasiness before giving it the breast.
