Typically an hour for each breast. Really depended sometimes on how full they were. But I tried to pump till I felt it was empty

how long did you pump for? @norarodgers

I had that problem too. I breastfed my daughter till she was 6-7 months old but when she was just born after she got out the hospital she would only drink a little at a time being she was so little so to keep them from overfilling and hurting I had to pump every 2 hours like clockwork and if I missed a pumping they would hurt terribly bad from being too full. I had to massage them and put warm compresses on them. As I pumped more and she began eating more during a feeding it got better but when I started work it got a bit harder but don't give up, it will get better

feed on demand and pump after every feeding every 2-3 hours & massage them all the time also a warm hot bath helps ease the pain
