Then place the jar in a kettle or pan of cold water, like the bottom of an oatmeal kettle. Leave the cover of the jar loose. Place it on the stove and let the water come to a boil and boil ten minutes, screw down the cover tight and boil ten minutes more, then remove from the fire, and allow it to cool in the water slowly so as not to break the jar. When partly cool put on the ice or in a cool place, and keep tightly covered except when the milk is poured out for use. The glass jar must be kept perfectly clean and washed {324} and scalded carefully before use. A tablespoonful of lime water to a bottle of milk will aid indigestion. Discard the bottle as soon as possible and use a cup which you know is clean, whereas a bottle must be kept in water constantly when not in use, or the sour milk will make the child sick. Use no tube for it is exceedingly hard to keep it clean, and if pure milk cannot be had, condensed milk is admirable and does not need to be sterilized as the above. _DIET._ 9. Never give babies under two years old such food as grown persons eat. Their chief diet should be milk, wheat bread and milk, oatmeal, possibly a little rare boiled egg, but always and chiefly milk. Germ wheat is also excellent. _EXERCISE._ 10. Children should have exercise in the house as well as outdoors, but should not be jolted and jumped and jarred in rough play, not rudely rocked in the cradle, nor carelessly trundled over bumps in their carriages. They should not be held too much in the arms, but allowed to crawl and kick upon the floor and develop their limbs and muscles. A child should not be lifted by its arms, nor dragged along by one hand after it learns to take a few feeble steps, but when they do learn to walk steadily it is the best of all exercise, especially in the open air. Let the children as they grow older romp and play in the open air all they wish, girls as well as boys. Give the girls an even chance for health, while they are young at least, and don't mind about their complexion. [Illustration] {325} Infant Teething. [Illustration] 1. REMARKABLE INSTANCES.--There are instances where babies have been born with teeth, and, on the other hand, there are cases of persons who have never had any teeth at all; and others that had double teeth all around in both upper and lower jaws, but these are rare instances, and may be termed as a sort of freaks of nature. 2. INFANT TEETHING.--The first teeth generally make their appearance after the third month, and during the period of teething the child is fretful and restless, causing sometimes constitutional disturbances, such as diarrhoea, indigestion, etc. Usually, however, no serious results follow, and no unnecessary anxiety need be felt, unless the weather is extremely warm, then there is some danger of summer complaint setting in and seriously complicating matters.
