Babies should not travel; that is obvious. But if a journey is unavoidable, the attendant difficulties and disadvantages may be greatly lessened by making certain preparations. If the baby is bottle-fed, the preparations will depend upon the length of the journey and whether or not it will be possible to have freshly prepared feedings, for each twenty-four hours, put on the train from laboratories along the way. If this is not possible and the journey is not to take more than twenty-four hours, the entire quantity of food, ice-cold, may be carried in a thermos bottle. The requisite number of sterile nursing bottles may be taken or one bottle which is boiled before each feeding. Or the milk may be prepared as usual and the bottles packed in a portable refrigerator. Such a refrigerator may be bought or one may be improvised. The bottles are placed in a covered pail and packed solidly in crushed ice; this is placed in a second pail or a box with a diameter which is at least two inches larger than the inner pail and the space between the two packed firmly with sawdust. Several thicknesses of newspapers should be pressed down over the top and a tight cover fitted to the outer receptacle. The sterile nipples may be taken in a sterile jar and a deep cup or kettle will be needed in which to warm the bottle before each feeding. It is usually possible to obtain water on the train which is hot enough for this, or cans of solid alcohol, a stand and a metal tray may be added to the traveling outfit. If fresh formulæ cannot be delivered to the train, daily, and the journey is to last more than twenty-four hours, one of the proprietary foods or a powdered milk will often prove to be a satisfactory solution to the problem of feeding the baby while traveling. The course to be followed, however, should be selected by your doctor. [Illustration: FIG. 67.—If traveling is unavoidable the baby will be comfortable and undisturbed in a basket converted into a bed. (By courtesy of the Maternity Centre Association.) ] The baby will usually travel more comfortably and sleep better if he is carried in a basket. A large market basket with a handle or a small clothes basket will serve. It may be lined with a sheet or a blanket; have a small hair pillow or folded blanket in the bottom and be made up like a crib. (Fig. 67.) If this basket stands on the car seat during the day, and on the foot of your berth at night, the baby will be cleaner, quieter and less exposed to drafts than if carried in the arms.
