We're going to a wedding tomorrow. DD is 9 weeks. I'd and been expressing successfully up to a few days ago, when I was ill, and now I can't seem to express more than a couple of ounces a day . I was planning to give her bottles in the evening and night so that I can have a few drinks. I don't want to get drunk but I'd been looking forward to a few glasses of champers. How much is ok?
