Mother’s milk is the best diet for a baby and it is recommended that the baby is kept only on mother’s milk for the first six months. As during pregnancy diet is of utmost importance so that your baby gets all the nutrients it needs. In fact, if the mother’s diet does not include all the nutrients the quality of the milk will not suffer as the body puts milk production on top priority and will use up the nutrients available in the body. The result will be that the mother’s nutritional need will be left unfulfilled. This is similar to the pregnancy state where the nutritional needs of the fetus were fulfilled before the mother.
