Once the alcohol is out of your blood stream its out of your
breast milk... so the only reason to pump
and dump is for comfort(if your over full) other than that its a waste to dump, so dont feel like you have to pump every ounce out as its not gonna make the alcohol leave any faster and missing one or two feeding really shouldnt have too much affect on your milk supply... if you really want to drink i would try offering a bottle before that night...
