Tasha, the blood alcohol in your milk will be the same as in your blood at the same time. It is strongly recommended that you consume no alcohol at all until at bub is at least 3 months, as their livers can't handle even a small quantity. It looks like your bub will be just 2 weeks old so I would not drink anything. Once she turns 3 months you can decide about drinking small amounts, like half a glass of wine, but no way would I drink 4 cruisers in one night while bfing. Sorry for the bad news hun, but there'll be plenty more NYEs.
