The toughening of the nipples should be begun eight weeks before the baby is expected. There are two general methods which seem to give about equally satisfactory results. One is to soften the skin, and the other is to harden it. In either case the nipples should first be scrubbed gently with a soft brush or cloth, warm water and soap, for about five minutes night and morning. After the scrubbing they should be rubbed with lanolin, cocoa butter or vaselin and covered with a piece of clean soft cloth or gauze, to protect the clothing. Or, they may be bathed with a wash consisting of equal parts of a saturated solution of boracic acid and 95 per cent alcohol. You will probably have to have a druggist prepare this for you because of the alcohol. But no matter which course is followed the care must be regular to be effective. You will find that matters will be simplified if you will assemble in one place and keep in readiness the soap, brush and lotion or ointment which you use each time, using them for no other purpose. =Care of the Teeth.= It is very important for the expectant mother to give her teeth scrupulous care from the beginning of pregnancy, for in addition to the ordinary wear and tear with which we all have to cope, her tendency to have an acid stomach makes her mouth acid and this is bad for her teeth. Accordingly, in addition to using dental floss and brushing your teeth after each meal, you should use an alkaline mouth wash several times daily, particularly after vomiting and before retiring, for much damage may be done by the acid secretions in the mouth if they are allowed to bathe the teeth during the long night stretches. Common baking soda (a teaspoonful to a tumbler of water), lime water or milk of magnesia all make excellent mouth washes. It is important, also, that you consult a dentist as soon as you know that you are pregnant and have any necessary repairs done promptly, for delay may be serious. COMMON DISCOMFORTS DURING PREGNANCY You may have a number of minor ills and temporary disturbances during pregnancy which are not serious but capable of making you very uncomfortable, and which you may sometimes relieve yourself. But should they be severe or persistent, you should consult your doctor at once. The most common of these minor discomforts may be grouped as digestive disturbances and “pressure symptoms.” Chief among the digestive disturbances are “morning sickness,” “heartburn,” “distress” and flatulence or “gas.”
