Hi,
Welcome to Share!
I recently learned that there are so many mamas out there that exclusively pump. There are moms of healthy full term babies who just don't want to nurse, so their moms pump and bottle feed them.
If you go to kellymom.com you can learn a lot more about it. I think baby center has a group for Exclusively Pumping mamas, I think two must haves are a hospital grade pump and a hands free pumping bra.
When my first son was in the nicu, I knew moms who pumped for a whole year and their babies got only *** milk because their moms were able to supply enough. If your baby is physically able to latch on, I'd keep working on it if its something you really want. Like Lindsay said, you could contact the La Leche League or you could just pump.
Good luck! Keep us updated!
