When can I stop pumping and dumping?

For the past three days I've have flu like symptoms. Felt so crappy, I had to succumb to medication yesterday. First time in a year and a half. I've been taking Tylenol cold flu day time every six hours since 11am yesterday. Just had another dose (two pills) at 5am this morning. For about half a day, I thought I was done with pumping, my son doesn't like the breast, my mom said "you've done it for 6 months, and it's okay if you decide to stop" so I thought I was. But then I think, "why don't I stop when I dry out?" It's already happening anyway. I guess what I'm getting at is, I just rather him to have at least 1-3 bottles of my milk while I can still give him that.
