The ordinary nursing bottle with nipple necessitates holding the bottle in a certain position, and when the valve nipples are used, the bottle should be held far enough away to allow this valve free action. To accomplish this I constructed a very simple wire holder for the bottle as shown in the illustration. Ordinary telephone wire will hold any bottle. The wire is bent to hook on the side of the crib, cradle or cab. - Contributed by W. A. Humphrey, Columbus, O.
