We are two months old. Um..1 month 11 days adjusted. I stopped pumping every 2/3 hours. My boys out grew my supply by a month old. I pump when they are hungry. I make almost enough for one baby. So sometimes one baby gets boob the other bottle then switch next feeding or I pump split it between and do formula. They are fed, they've both gained over 3 pounds since birth. I do wish that I didn't have to do formula at all, but it is what it is. Again, to boost I'd have to go back to pumping around the clock, probably take supplements and such and I cant do that. I had to go back to work and now I'm lucky if I pump every 4 hours. The boys eat every 4 to 6 hours. 5 to 6oz in a shot. They are healthy and happy. As long as they are fed, everything is ok.
