Consideration of the effects of alcohol and breastfeeding needs to take into account various factors, such as how much alcohol is consumed, patterns of consumption, the time between consumption and nursing an infant, and the age of the infant. What a mother eats and drinks affects the taste of her milk and this can create nursing issues. Research has also shown that alcohol impairs the ‘let-down’ reflex, making it harder for an infant to get milk to come out. Although more research is needed in this area, we can argue that biological delays regarding the release and volume of milk can have direct effects on infants, and can lead to decisions to introduce formula feeding.
