Moreover, the arm on which it is carried must be changed from time to time, otherwise deformity may result from leaning always on one side, or a tendency may be contracted to turn the eyes in one direction or squint.
However, I consider that from almost the earliest age infants ought to be taken out in perambulators, and, if they are properly dressed, I feel sure that there need be no fear of their thus being more liable to take cold than if they were carried.
