Tell her no no no!!! That's really not a good idea EVERYTHING your friend eats, smokes, drinks, etc. Will affect her childs health! Drinking liquor while breastfeeding is so very dangerous. Wow. Its in her milk when she's feeding her baby. It doesn't matter if the baby eats food or not that has nothing to do with the fact that her child is ingesting liquor. Tell her if she wants to party so bad then STOP breastfeeding.
