N.C.
My baby is 4 months old now and has been sleeping through the night since she was 2 months. The first week of her sleeping through the night I had to get up to pump becuase I was in a lot of pain. After the first week though I didn't have to pump and I still hve enough milk for baby throughout the day and early morning.
It just got to the point where sleep was more important than getting up in the middle of the night to pump! haha! I now sleep very comfortable at night and by morning my daughter has a really big breakfast. I hope this helps.
