Pain in the bowels in young infants is indicated by moaning cries, pallor, peculiar drawing of the corners of the mouth, twitching of the face during sleep, sometimes supposed to be due to "angel whispers;" the abdomen is usually bloated; infant kicks and frequently passes wind. The principal cause is indigestion. If the feet are allowed to get cold, pain in the bowels will generally result. It is also occasioned by the irritation of worms. Infants often manifest great eagerness to nurse.
Regulate the diet carefully, apply fomentations to the bowels, and warmth to the feet. A drop or two of peppermint essence in a few teaspoonfuls of water, will generally relieve the pain from gas in the bowels.
