Hi, My twins were in the NICU 5 years ago (can't believe it's been so long!)
I second the suggestion of power pumping - just try it and see if it helps
|If you are exclusively pumping, try a round of “power pumping” -- use your breast pump for twenty minutes, stop for twenty minutes. Repeat -- pump for twenty minutes, stop for twenty minutes, and then repeat a third time. This will provide one hour of pumping in a two-hour period. Then resume your regular pumping schedule. Some mothers find this provides a jump-start to their milk production, much as an infant going through a growth spurt would ask to feed more frequently. Try power pumping twice a week for long-term maintenance of supply when exclusively pumping.
I also second the seggestion of getting up one time at night - prolactin is at it's highest then and you should be able to pump more... plus first thing in the morning was always a good pumping session for me...
and finally, just get her home
once you start to NURSE her your supply will increase, though it may take time. Nothing makes milk like breastfeeding
