2. A breastfeeding mother has to eat more in order to make enough milk. Not true! Women on even very low calorie diets usually make enough milk, at least until the mother's calorie intake becomes critically low for a prolonged period of time. Generally, the baby will get what he needs. Some women worry that if they eat poorly for a few days this also will affect their milk. There is no need for concern. Such variations will not affect milk supply or quality. It is commonly said that women need to eat 500 extra calories a day in order to breastfeed. This is not true. Some women do eat more when they breastfeed, but others do not, and some even eat less, without any harm done to the mother or baby or the milk supply. The mother should eat a balanced diet dictated by her appetite. Rules about eating just make breastfeeding unnecessarily complicated.
