If a child lie alone, place him fairly on his aide in the middle of the bed; if it be winter time, see that his arms and hands be covered with the bed-clothes; if it be summer, his hands might be allowed to be outside the clothes. In putting him down to sleep, you should ascertain that his face be not covered with the bedclothes; if it be, he will he poisoned with his own breath—the breath constantly giving off carbonic acid gas; which gas must, if his face be smothered in the clothes; be breathed—carbonic acid gas being highly poisonous.
You can readily prove the existence of carbonic and gas in the breathing, by simply breathing into a little lime-water; after breathing for a few seconds into it, a white film will form on the top; the carbonic acid gas from the breath unites with the lime of the lime-water and the product of the white film is carbonate of lime.
189. Do you advise a bedroom to be darkened at night?
Certainly: a child sleeps sounder and sweeter in a dark than in a light room. There is nothing better for the purpose of darkening a bedroom, than Venetian blinds. Remember, then, a well-ventilated, but a darkened, chamber at night. The cot or the crib ought not to face the window, "as the light is best behind." [Footnote: Sir Charles Locock in a Letter to the Author. ]
190. Which is the beat position for a child when sleeping—on his back, or on his side?
His side: he ought to be accustomed to change about on the right side one night, on the left another; and occasionally, for a change, he should lie on his back. By adopting this plan, you will not only improve his figure, but likewise his health. Lying, night after night, in one position, would be likely to make him crooked.
191. Do you advise, in the winter time, that there should be a fire in the night nursery?
Certainly not, unless the weather be intensely cold. I dislike fires in bedrooms, especially for children; they are very enervating, and make a child liable to catch cold. Cold weather is very bracing, particularly at night "Generally speaking," says the Siecle, "during winter, apartments are too much heated. The temperature in them ought not to exceed 16 deg. Centigrade (59 deg. Fahrenheit); and even in periods of great cold scientific men declare that 12 deg. or 14 deg. had better not be exceeded. In the wards of hospitals, and in the chambers of the sick, care is taken not to have greater heat than 15 deg.. Clerks in offices, and other persons of sedentary occupations, when rooms in which they sit are too much heated, are liable to cerebral [brain] congestion and to pulmonary [lung] complaints. In bedrooms, and particularly those of children, the temperature ought to be maintained rather low; it is even prudent only rarely to make fires in them, especially during the night"
If "a cold stable make a healthy horse," I am quite sure that a moderately cold and well-ventilated bedroom helps to make a healthy child. But, still, in the winter time, if the weather be biting cold, a little fire in the bedroom grate is desirable. In bringing up children, we must never run into extremes—the coddling system and the hardening system are both to be deprecated; the coddling system will make the strong child weakly, while the hardening system will probably kill a delicate one.
A child's bed ought, of course, to be comfortably clothed with blankets—I say blankets, as they are much superior to coverlids; the perspiration will more readily pass through a blanket than a coverlid. A thick coverlid ought never to be used; there is nothing better, for a child's bed, than the old-fashioned patchwork coverlid, as the perspiration will easily escape through it.
