CHAPTER II.
THE GENERAL SIGNS OF DISEASE IN INFANCY AND CHILDHOOD.
The signs of disease at all ages may be referred to one or other of three great classes: disorder of function, alteration of temperature, complaint of pain.
In the infant it is the last of these which very often calls attention to the illness from which it is suffering. Cries are the only language which a young baby has to express its distress; as smiles and laughter and merry antics tell without a word its gladness. The baby must be ill, is all that its cries tell one person; another, who has seen much of sick children, will gather from them more, and will be able to judge whether its suffering is in the head, or chest, or stomach. The cries of a baby with stomach-ache are long and loud and passionate; it sheds a profusion of tears; now stops for a moment, and then begins again, drawing up its legs to its stomach; and as the pain passes off, stretches them out again, and with many little sobs passes off into a quiet sleep. If it has inflammation of the chest it does not cry aloud, it sheds no tears, but every few minutes, especially after drawing a deeper breath than before, or after each short hacking cough, it gives a little cry, which it checks apparently before it is half finished; and this, either because it has no breath to waste in cries, or because the effort makes its breathing more painful. If disease is going on in the head, the child utters sharp piercing shrieks, and then between whiles a low moan or wail, or perhaps no sound at all, but lies quiet, apparently dozing, till pain wakes it up again.
It is not, however, by the cry alone, or by any one sign of disease, that it is possible to judge either of its nature or of its degree, but the mention of this serves merely as an illustration, which anyone can understand, of the different meanings that even a baby's cry will convey to different persons.
When a child is taken ill, be the disease from which it is about to suffer what it may, there is at once a change from its condition when in health, such as soon attracts the attention even of the least observant. The child loses its appetite, is fretful and soon tired, and either very sleepy or very restless, while most likely it is thirsty, and its skin hotter than natural. In many instances, too, it feels sick or actually vomits, while its bowels are either much purged or very bound. If old enough to talk, it generally complains of feeling ill, or says that it has pain in some part or other, though it is by no means certain that a little child has described rightly the seat of its pain; for it very often says that its head aches or that its stomach aches, just because it has heard people when ill complain of pain in the head or in the stomach. Some of these signs of illness are, of course, absent in the infant, who can describe its feelings even by signs imperfectly; but the baby loses its merry laugh and its cheerful look; it ceases to watch its mother's or its nurse's eye as it was used to do, though it clings to her more closely than ever, and will not be out of her arms even for a moment; and if at length rocked to sleep in her lap, will yet wake up and cry immediately on being placed in its cot again.
Symptoms such as these are sure to awaken the mother's attention to her child, and the child's welfare and the parent's happiness alike depend, in many instances, on the way in which she sets about to answer the question, 'What is the matter?'
Some mothers send at once to the doctor whenever they see or fancy that anything ails their child. But this way of getting rid of responsibility is not always possible, nor, indeed, on moral grounds, is it always desirable, for the mother who delegates each unpleasant duty to another, whether nurse, governess, or doctor, in order to save herself trouble or anxiety, performs but half a mother's part, and can expect but half a mother's recompense of love.
Whenever a child is unwell, a mother may do much to ascertain what is the matter, and may by the exercise of a little patience and common sense save herself much needless heart-ache, and her child much suffering.
The first point to ascertain is the presence or absence of fever; that is to say, whether, and how much, the temperature of the body is higher than natural. If the temperature is not higher than natural, it may be taken as almost certain that the child neither has any inflammatory affection of the chest, nor is about to suffer from any of the eruptive fevers. The temperature, however, cannot be judged of merely by the sensation conveyed to the hand, but must be ascertained by means of the thermometer.[4] In the case of the grown person the thermometer is placed either under the tongue, the lips being closed over it, or in the armpit, and is kept there five or six minutes. In young children, however, neither of these is practicable, and I prefer to place the instrument in the groin, and crossing one leg over the other, to maintain the thermometer there for the requisite five minutes. The temperature of the body in health is about 98.5° Fahr. in the grown person, and very slightly higher in childhood; but any heat above 99.5° may be regarded as evidence that something is wrong, and the persistence for more than twenty-four hours of a temperature of 101° and upwards, may be taken as almost conclusive proof of the existence of some serious inflammation, or of the onset of one of the eruptive fevers.
