Besides fresh air, light is an indispensable requisite to the health of children. Nothing can compensate for the absence of its beneficial effects. It is to be remembered, however, that during the first week or two the eyes of the new-born babe are not strong enough to bear the full glare of light. The first eight days of its existence should be spent in a half-darkened room. Gradually the apartment may be brightened, until finally, after about two weeks, the young eyes become entirely accustomed to the light, and may be exposed to it without injury. A neglect of this precaution is one of the most common causes of the bad inflammation of the eyes so frequently met with among young infants. After the sight has become quite strong, a bright room will strengthen the eyes, not weaken them; for light is the natural stimulant of the eye, as exercise is of the muscles, or food of the stomach.
Scrofulous diseases are the heritage of those children who are deprived of a plentiful supply of pure air and light. A distinguished writer upon the laws of health ascribes to the careful avoidance of the salutary influence of air and light by so many young girls, who are fearful of walking out while the sun is powerful, much of their sickly appearance, the loss of consistency of their bones, and their being able to afford but a deformed temple to the immortal soul.
Humboldt states that, during a five years' residence in South America, he never saw any national deformity amongst the men or women belonging to the Carif, Muyscas, Indian, Mexican, or Peruvian races. If parents in our own country were to accustom their daughters from an early age to daily exercise in the open air and sunlight, there would be fewer weak backs requiring the support of apparatus from the surgical-instrument maker, and less pallor in lips and cheeks to be remedied by iron from the shop of the apothecary.
EXERCISE IN CHILDHOOD.
The first exercise which a child obtains, is had of course in its nurse's arms. Are there any directions, then, to be noticed in regard to the manner of carrying an infant?—Dr. Eberle gives the following useful advice upon this subject:—'The spine and its muscles seldom acquire sufficient strength and firmness before the end of the third month to enable the child to support its body in an upright position without inconvenience or risk of injury. Until this power is manifestly acquired, the infant should not be carried or suffered to sit with its body erect, without supporting it in such a manner as to lighten the pressure made on the spine, and aid it in maintaining the upright posture of its head and trunk; therefore, at first (a few days after birth), the infant should be taken from its cradle or bed two or three times daily and laid on its back upon a pillow, and carried gently about the chamber. After the third or fourth week, the child may be carried in a reclining posture on the arms of a careful nurse, in such a manner as to afford entire support both to body and head. This may be done by reclining the infant upon the forearm, the hand embracing the upper and posterior part of the thighs, whilst its body and head are supported by resting against the breast and arm of the nurse. When held in this way, it may be gently moved from side to side, or up and down, while it is carefully carried through a well-ventilated room.'
After the child is three months old, it will probably have become strong enough to maintain itself in a sitting position. It may then be carried about in this upright posture, with the spine and head carefully supported by the nurse, which aid ought not to be withdrawn until the age of six or seven months.
'In lifting young children,' as has been well observed by Dr. Barlow, 'the nurse should be very careful never to lay hold of them by the arms, as is sometimes thoughtlessly done; but always to place the hands, one on each side of the chest, immediately below the armpits. In infancy the sockets of the joints are so shallow, and the bones so feebly bound down and connected with each other, that dislocation and even fracture of the collar-bone may easily be produced by neglecting this rule. For the same reason, it is a bad custom to support a child by one or even by both arms, when he makes his first attempt to walk. The grand aim which the child has in view, is to preserve his equilibrium. If he is partially supported by one arm, the body inclines to one side, and the attitude is rendered most unfavorable to the preservation of his natural balance; and consequently, the moment the support is in the least relaxed, the child falls over and is caught up with a jerk. Even when held by both arms, the attitude is unnatural and unfavorable to the speedy attainment of the object. To assist the child, we ought to place one hand on each side of the chest in such a way as to give the slightest possible support, and to be ready instantly to give more if he lose his balance. When this plan is followed, all the attitudes and efforts of the child are in a natural direction; and success is attained not only sooner, but more gracefully, than by any ill-judged support given to one side.
'There is one very common mode of exercising infants, which we think deserves particular notice: we mean the practice of hoisting or raising them aloft in the air. This practice is of such venerable antiquity, and so universal, that it would be vain to impugn it. The pleasure, too, which most children evince under it, seems to show that it cannot be so objectionable as a cursory observer would be disposed to consider it. Still there are hazards which ought not to be overlooked. The risk of accident is one of some amount: children have slipped from the hands, and sustained serious injury. Some people are so energetic as to throw up children and catch them in descending. This rashness there can be no hesitation in reprobating; for, however confident the person may be of not missing his hold, there must ever be risks of injury from the concussion suffered in the descent, and even from the firmness of the grasp necessary for recovering and maintaining the hold. The motion of the body, too, has a direct tendency to induce vertigo; and when the liability of the infant brain to congestion and its consequences is considered, when the frequency of hydrocephalus in infants is borne in mind, an exercise which impels blood to the brain will not be regarded as wholly insignificant. There is one more objection which seems not to have attracted attention. The hold taken of the child in the act of hoisting him is by the hand grasping the chest. The fingers and thumb, placed on each side of the breast-bone, compress the ribs; and any one with the hand so placed will at once perceive that if the pressure were strong, and the resistance from the elasticity of the ribs weak, the impression on the chest resulting would correspond exactly with the deformity named chicken-breast. That any force is ever used capable of inducing speedily such a change, is in the highest degree improbable; but that reiterated pressure of this kind, however slight, would in a weakly child have power to impress and distort the chest, few, we imagine, will doubt.'
LEARNING TO WALK.
When two or three months old, the infant may be placed on a soft mattress upon the floor or on the carpet. He can then toss his limbs about without danger, and develope the powers of his muscular system.
