Okay so my goal is to ebf my baby until he is a year old at least. I have a spectra pump coming this Friday (I feel my Medela pump just isn't working well with me). I work full time pumping 3 times during the 8 hours I'm gone and feed baby emedietely upon returning home... a friend of mine recently put a huge worry in my head and I feal maybe my goal of pumping at work and maintaining a supply until baby is 1 year (i never want to use formula)is maybe a long shot?? Is it at all possible for me to maintain a supply enough to feed my baby while I'm away and at home without resorting to supplimenting with formula for the next 9 months??

**edit **I pump any were from 12 to 25 Oz a day in the 3 times I pump. And baby drink about 9- 14 Oz while I'm gone...
