Hi Sharon
Some pp do advise to express and throw away. Again, it's really up to you. You may want to just follow or maybe you can test once or twice and see what works for you and baby. For myself, I've not thrown any milk away. If my girl wakes up later in the night to feed, I just feed as usual. If she sleeps on, then I just express as usual and keep. On a few occasions, right after I drink the DOM, she wakes up and wants to feed again. At such times, I have still given her my breast eventhough I'd just drank DOM. I try to minimise such occasions by making sure that she's soundly asleep before I drink but well, babies are unpredictable right.
Touch wood, my girl is well and healthy. Doc says she's growing v well. She's never refused the breast after I drink DOM and she's never refused the milk expressed after a DOM.
Time lag - during the first month, at night - there would be about 3-4 hours between each feed or expression. So apart from the few times that she woke up, 2.5 hours is the shortest average time lag between DOM intake and feed/expression.
[Not sure if this is relevant in any way, but my alcohol tolerance has always been quite good, so maybe my body is used to processing and dissipating the alcohol
