This is called nursing strike or nipple confusion.

Some babies, especially those of approximately 2-4 months of age, become increasingly upset with the spray of milk which may increase their aversion to nursing to the point of refusing the breast (a nursing strike).

In 2011, the suicide of a nurse who worked at Asian Heart Institute lead to a series of nursing strikes across the city related to wages, working conditions and the 2 year bond that private hospitals hold on nurses' graduation certificates.

Studies have shown that babies take around 20% less milk if there's alcohol present, so they'll need to feed more often - although infants have been known to go on 'nursing strike', probably because of the altered taste of the milk."
