Inflammation of the Breasts and Navel
New-born infants are liable to a singular inflammation and enlargement of the breasts, which is often very injuriously treated by squeezing, sucking, or pressing them, in order that they may be "milked out," as ignorant nurses talk of. In moderate cases of this kind, nothing more is necessary than to apply a piece of linen moistened with a little sweet oil; or a weak solution of the muriate of ammonia in vinegar and water, in the proportion of a drachm of the ammonia to four ounces of vinegar. The solution ought to applied warm by moistening pieces of linen with it, and laying them over the affected parts.
Inflammation and consequent ulceration about the navel is a frequent occurrence during the first nine or ten days after birth. The most common cause is deficient attention to cleanliness, particularly in not clearing away the white caseous matter from about the umbilicus. A solution of the sulphate of copper, in the proportion of ten grains to an ounce of water, may be applied once or twice daily, and the parts afterwards covered with lead ointment, where there is cations are made, the parts should be carefully washed with lukewarm water, at least twice daily.
