The question of suitable clothing will be important, and will decide the advisability as to when the baby should go out. Every baby should be dressed in wool weather is not too distinctly bad. Remember always to [Transcriber's note: words missing in text] from neck to ankles. Its head should be warmly clad. Dressed thus and well wrapped in blankets, a healthy child is ready for an out-door trip at any time, if the [Transcriber's note: words missing in text] have plenty of blankets below the child as well as above it, if it is in a baby carriage. In very cold weather the child should be buried in blankets, and a hot water bottle can be wrapped in near his feet. Great care must be taken that the water in the bottle is not too hot, and that it does not actually touch the skin. No matter how many or how few blankets are used, the face should be exposed directly to the fresh air. When the air is very gusty, or high, a light veil can be laid over the face, but never at any other time. AIR BATHS FOR BABIES.--Babies necessarily require plenty of exercise and plenty of fresh air, as has been pointed out. It is a splendid custom to allow the baby to lie naked after his bath for half an hour. If the room is comfortably warm, select a spot that is free from draughts, and lay the baby on a pillow or two and let him kick and coo. In the sun by the window, his head and especially the eyes shaded from the direct rays of the sun, is an excellent place in the summer time. The influence of the direct sun rays on the little naked body is conducive to good sturdy health, good nerves, and sound sleep. CHAPTER XVIII BABY'S GOOD AND BAD HABITS.
