When a month or six weeks has elapsed, the child, if healthy, may sleep alone in a cradle or cot, care being taken that it has a sufficiency of clothing, that the room in which it is placed is sufficiently warm, viz. 60 degrees, and the position of the cot itself is not such as to be exposed to currents of cold air. It is essentially necessary to attend to these points, since the faculty of producing heat, and consequently the power of maintaining the temperature, is less during sleep than at any other time, and therefore exposure to cold is especially injurious. It is but too frequently the case that inflammation of some internal organ will occur under such circumstances, without the true source of the disease ever being suspected. Here, however, a frequent error must be guarded against, that of covering up the infant in its cot with too much clothing throwing over its face the muslin handkerchief and, last of all, drawing the drapery of the bed closely together. The object is to keep the infant sufficiently warm with pure air; it therefore ought to have free access to its mouth, and the atmosphere of the whole room should be kept sufficiently warm to allow the child to breathe it freely: in winter, therefore, there must always be a fire in the nursery.
Chemical peel uses a chemical solution to improve and smooth the texture of the facial skin by removing its damaged outer layers. A peel removes several layers of sun damaged skin cells, leaving fresh skin which has a more even surface and colour. It may stimulate new collagen to be formed improving skin texture. Peels may result in superficial, moderate depth or deep skin injury.
