I'm trying to breastfeed my 3 week old baby. I am expressing using an electric pump as she was premature so I had to establish a supply this way and she's not yet exclusively breastfeeding. My supply from my left breast is fine (usually get around 60ml from expressing alone) but my right breast is a massive underachiever (only get 5-15ml at a time. I know it's not unusual to have an uneven supply and I've had surgery on my right breast so it's not surprising. But is there anything I can do to help it produce more?
