Started pumping with the hospital grade pump yesterday and I can say it's discouraging to be pumping ever couple or hours and to get nothing, I have to remind myself that my body wasn't quite ready to have to do all these things just yet so since I had him 8 weeks early...
Don't feel discouraged sweetie. I had ny son 3 months early and it took 4 days for my milk to come in. Now my son will be 1 month old this friday and I have tons of milk stored in ny deep freezer. Keep try ans drink plenty of water. Set an alarm to pump every 3 hours.
