I think it is okas long as you are sensible about it. If you are looking for information the ABA has produced a brochure recently with a lot of information and also has a table to work out how long it takes to eliminate alcohol from your breastmilk. It is on their website. Pumping and dumping does not eliminate alcohol from your breastmilk btw, time is the only thing that works, howeveryou might still have to pump and dump to avoid mastitis and maintain supply.

eta I don't think that a woman should drink in the newborn phase though as the feeding pattern is variable and bf is still being established, for the first 6 weeks or so.
