Re: Less milk post surgery?
Getting 5-8 oz right after nursing means you had some oversupply going on. A more normal amount to pump after nursing is an ounce or two, or even nothing. So that 2-3 oz you're now getting after nursing- that's actually quite good!
When do you have to return to work? Right now, I would encourage you to focus on simply nursing the babies on demand, and not supplementing with bottles. If you need to give them bottles so that they can "practice" for when you're on the job, keep the bottles small (1-2 oz at most) and limit them to once a day. Right now you want the babies to be doing the work of getting your supply where it needs to be.
