Quoting Cristina Mudd:" im going through the same ... i cant express more then 30ml during the day and 50-60 1st time in the ... [snip!] ... cause she is not gaining much wight atm and i think its because of my bad milk....shes almost 2 weeks old (29 weeker preemie)"All I can say is keep at it! It takes time. My girls were supplemented for a while in hospital before I was making enough milk for them, but I did end up getting plenty in eventually and didn't have to supplement either of them after two weeks. I was waking up during the night too to pump (every 3 hours through day and night for 20 minutes). It was a full-time job but worth it in the end although it felt like torture while I was doing it!
