_Should the infant sleep alone?_--We have mentioned the danger of being overlain to which it is exposed when in bed with its mother or nurse. On the other hand, it must be remembered that an infant keeps warm with difficulty even when well covered, and that contact with the mother's body is the best way of securing its own warmth. Hence, during the first months the child had better be allowed to sleep with its mother. How, then, can the risk of being suffocated, which is no imaginary one, be lessened? The following rules are those given by a physician of reputation, to prevent an infant from being accidentally overlain. 'Let the baby while asleep have plenty of room in the bed. Do not allow him to be too near, or, if this be unavoidable from the small size of the bed, let his face be turned to the opposite side. Let him lie fairly, either on his side or on his back. Be careful to ascertain that his mouth be not covered with the bed-clothes. Do not smother his face with clothes, as a plentiful supply of pure air is as necessary as when he is awake. Never let him lie low in the bed. Let there be no pillow near the one his head is resting on, lest he roll to it and bury his head in it. Remember a young child has neither the strength nor the sense to get out of danger; and if he unfortunately either turn on his face or bury his head in a pillow that is near, the chances are that he will be suffocated, more especially as these accidents usually occur at night, when the mother or the nurse is fast asleep. Never entrust him at night to a young, giddy, and thoughtless servant. A foolish mother sometimes goes to sleep while allowing her child to continue sucking. The unconscious babe, after a time, loses the nipple, and buries his head in the bed-clothes. She awakes in the morning, finding, to her horror, a corpse by her side! A mother ought therefore never to go to sleep until her child has ceased sucking.' When a couple of months have elapsed, the child, if a healthy one, may sleep alone. What the child sleeps in is not a matter of great moment, provided it has a sufficiency of clothing, and be not exposed to currents of air. A large clothes-basket will serve all the purposes of a crib. The mistake is often made of burying the child under too heavy a mass of bed-clothes in a warm room when asleep. And this inconsistency is committed by the very mothers who scantily clad the child during the day in order to inure it to the cold. The great transition from its wrappings by night to those by day is injurious to the health and comfort of the infant.
