Your milk is your blood, the better your blood, the better the baby. Books I have read say Mom's do well to juice fast. in your case you drink all the juices and water you desire. Herbal teas also like Red Raspberry to build strong organic iron. You do not take the dewormer because it may dry you up a little. You take oregano oil and olive leaf, this also passes to baby and does you both good.
Everything you eat and drink enters your milk, so you decide if baby gets fruits, berries, and nuts or hamburgers?
