The most healthy infant, even though it be fed at a normal breast, often expels a portion of each feeding. This is an act of regurgitation rather than vomiting, and is, in reality, a natural method of relieving an overburdened stomach.

Vomiting proper is preceded by the sensation of nausea; is followed by lassitude, and is often attended by fever. It indicates some disorder of the stomach. For its relief, perfect rest for the whole body; several hours' starvation, or rest for the stomach, and a reduction in the quantity and strength of the food, are necessary. Bits of ice, soda-mint, lime-water, and a mixture of equal quantities of cinnamon-water and lime-water, in tea-spoonful doses, are simple and efficient remedies; a weak mustard plaster placed over the pit of the stomach is always useful. Should the symptom be obstinate, however, the case becomes too serious for the mother to manage on her own responsibility.
