My lo should arrive any time now, and im planning on bf. iv got a wedding when lo will be approx 7 weeks, and want to have a drink while there. The info iv read regarding this is confusing, I know I could express but does having baby on a bottle for the day seriously affect ur supply. And does the alcohol remain in milk/ breast until its removed ( does that make sense) or does it naturally leave ur system? What does everyone do regarding alcohol?
