Children's Sleep.--This most important matter of good sleep for the child depends not only on health of body but on ease of the infant's mind. It is wrong to treat the child otherwise than through the understanding, where he is afraid, or in a strange place. Waking up, after being put to sleep in a strange room, the little one may receive a shock which may prevent sleep for the rest of the night. If he be patiently soothed and matters explained, all will be well; but it is a great cruelty to thrash or threaten in such a case. To frighten a child with ghost stories, or "Bogies," IS TO COMMIT A SERIOUS CRIME. It is not dealt with by the law, but it certainly deserves to be. Never bring before a child's mind any _imaginary terrors_; rather teach it to understand them in such a way as to remove any cause of fear. But do not _force_ a child to examine an object which it fears, you may do terrible damage before you can explain. All fears should be most carefully dealt with, and no force employed; the little one who has no imaginary terrors, and is kindly taught to think every fearful image at bottom some innocent cloak or shadow, will sleep soundly and grow healthy in mind. When, however, ill-health is the cause of wakefulness, other means must be used. Cold feet, and chilly feelings generally, frequently keep children from sleep. Pack in such cases the lower limbs up to the waist in thick folded flannel FOMENTATION (_see_). This will often not only give sleep, but prevent more serious trouble. All soothing powders and narcotic drugs should be most strictly avoided. Often the child is sleepless from feverish heat instead of coldness; then cooling applications should be used (_see_ Children in Fever). These may take the form of two caps for the head of thickest cotton cloth: one, tight fitting, to be wrung out of cold water and put on, the other, looser and dry, to be put on over the first. This alone will often secure a night's sleep. Or the head may be soaped (_see_ Head, Soaping). It is inadvisable to rock a child to sleep, it will go to sleep if comfortable. Children's Strength.--The question often arises as to the ability of children to bear certain kinds of treatment. It must ever be remembered, both in hot and cold applications, that the infant should be _gently_ dealt with. Violent cold and burning heat must alike be avoided. With a gentle application of heat before bracing cold is used, considerable power of endurance is imparted. Strong blisters and violent medicines should never be used. Very much less treatment will affect the infant than that required for an older child. And in almost every case the most durable cures are reached by gradual progress.
