Dr. Dewees mentions a nurse who, from a foolish fondness for displaying them, made the children consigned to her charge sit perfectly upright before they were a month old. It is truly ludicrous, he says, to see the little creatures sitting as straight as if they were stiffened by a back board. It is truly _horrible_, I should say, rather than ludicrous. Crooked spines must be the inevitable consequence, if nothing worse. The practice of bracing children, as it is called, by straps, back boards, corsets, &c., where it has produced any effect at all, has always had a tendency to crook the spine. This may be seen first, by observing one shoulder to be lower than the other, and next by a projection of the part of the shoulder blades next to the spine. Whenever these changes begin to appear, it is time to send for a physician, though it may often be too late to effect a cure. But on the general subject of bracing and corseting, I have treated at sufficient length elsewhere. There is another error committed in carrying children in the arms. The head of the infant is often permitted either to hang constantly on one side, or to roll about loosely; as if it hardly belonged to the body. In the former case there is danger of producing a habit of holding the head upon one side, which it will be very difficult to overcome; in the latter, the spinal marrow itself may be injured--which would produce alarming and perhaps fatal consequences. But all these evils, as has already been said, may be prevented, if the hand is placed so as to support the head and shoulders. Let not the mother, however, who reads this work, trust the matter wholly to a nurse; she must see to it herself; else she incurs a most fearful responsibility. The suggestions I have made are the more important in the case of children either very fleshy or very feeble, and of those disposed to rickets or scrofula; but they are important to all. I have said that the motion of the child, on the arm, should be gentle. Many are in the habit of tossing infants about. There can be no objection to a slight and slow movement up and down, for a minute or so at a time; indeed, it is rather to be recommended, as likely to give strength and vigor no less than pleasure to the child. But when such movements are carried to excess, so as to frighten the child, they are highly reprehensible. The shock thus produced to the nervous system has sometimes been so great as to produce sudden death. Nor is it safe to run, jump, or descend stairs hastily or violently, with a child in our arms; and for similar reasons.
