Hi M.
I breastfed until my som was about 10 months old, but did have to supplement when I returned to work. I am a teacher and was not able to pump as often as necessary to keep up with his needs. I do agree though that you should not supplement if at all possible at first. Your body needs to build up its supply. On that note, however, my milk was slow to come in and my pediatrician told me to breast feed first and then use a bottle until my milk came in when by day 4 it still was not there (didn't come in until day 6) so I am glad I had some for backup.
Talk with your ped. or the hospital though. I was lucky that a family friend was a lactation consultant, so she helped me with the pump and all that fun stuff. I don't know why it didn't work for you last time, but maybe they can help. If it help, I will say that the physical needs to drop off quickly, although I remember how exhaustign it is when nobody could help with those middle of the night feedings! IT does get better!!!!
Bottom line, do what is right for you. Yes, brestfeeding is the best nutritionally, but many of us were raised on formula and turned out just fine. IF you want to breastfeed though, don't be afraid to ask for help. THat is what they are there for. Good luck and keep us updated!
