They sell strips at BabiesRUs that test for alcohol. I used them often! When K was 8 weeks old I had my 1st outing & had a few beers. I went home, pumped, & tested. (dd was already sleeping thru the night, but
if I had had to feed her soon after or even a few hours after, I probably would have given her formula to be on the safe side)
If the milk tests postive, I dumped.
If it tested negative, I kept it. Some alcohol affected my milk differently along w/other factors as it does when are not worried about BF, ykwim?
And I don't know about your household, but it wasn't just the milk I was worried about.
If I drank too much & stayed out too late, I would want to sleep in & probably wouldn't feel 100% the next day and dd was still on her regular schedule, waking up at 7am or some god-awful hour! So, I usually opt for only a couple drinks anyways, unless
Dh promises to get up her with.....which does not happen often, lol.
