I'm on the tail-end of the flu myself right now, DD tested positive for flu yesterday. My doc said tamiflu is not for babes under 1 (as mine is), and that it's only beneficial to adults if given w/i the 1st 48 hrs. or so. (Made me so mad since I *was* at the doc then, but they didn't test me for it, even though I have a 6.5 mon.-old. GRrr.) But as far as breastfeeding goes, it's pretty standard. They don't know how much goes in breastmilk, but it's probably negligible. Hope this helps. I know--oh I know!--that the flu sucks. As my doctor said (when I went back to her later in the week with a horrible cough), a couple days into the flu, and you understand why some older people die from it. Hope she avoids it and her DC gets better soon. Sorry about TMI--I've been cooped up with the babe all week.
