Another matter not to be forgotten is the confidence to be reposed in the doctor--the readiness to acquiesce in his sometimes visiting the child more frequently in the course of an illness than the symptoms may seem to you to require. Were you involved in some civil action, in which your succession to large property was involved, you would scarcely expect your solicitor to give you his opinion on all the questions at a single interview. In the same way, the doctor, even the most experienced, may need to visit his little patient several times before he can feel quite certain as to the nature of the disease that is impending, while he may not wish to alarm you by suggesting all the possibilities that are present to his mind. The child after a restless night may be asleep, and it may be most undesirable to wake him; or he may be excessively cross and unmanageable, so that it is impossible to listen to his chest; or it may be very important to ascertain whether the high temperature present in the morning has risen still higher towards night, or whether, after free action of the bowels, it has fallen a degree or two, showing that no fever is impending, but that the undue heat of the body was occasioned by the constipation. Or, again, some remedy may have been ordered, of the effect of which the doctor does not feel quite sure: he wishes to see for himself whether it is right to continue or wiser to suspend it. The wise physician, like the able general, leaves as little as may be to chance. Nearly forty years ago, in addressing a class of medical students, I said to them: 'If you are carefully to observe all the points which I have mentioned, and to make yourselves thoroughly masters of a case, you must be lavish of your time; you must be content to turn aside from the direct course of investigation, which you would pursue uninterruptedly in the adult, in order to soothe the waywardness of the child, to quiet its fears, or even to cheat it into good humour by joining in its play; and you must be ready to do this, not the first time only, but every time that you visit the child, and must try to win its affections in order to cure its disease. If you fail in the former, you will often be foiled in your attempts at the latter. Nor is this all; you must visit your patient very often if the disease is serious in its nature and rapid in its course. New symptoms succeed each other in infancy and childhood with great rapidity; complications occur that call for some change in your treatment, or the vital powers falter suddenly when you least expect it. The issues of life and death often hang on the immediate adoption of a certain plan of treatment, or on its timely discontinuance. Do not wait, therefore, for symptoms of great urgency before you visit a child three or four times a day; but if the disease is one in which changes are likely to take place rapidly, be frequent in your visits as well as watchful in your observation.'
