I didn't take the time to read all your responses, so might be repeating. Just wanted to let you know that I was unable to breast feed either of my kids, but did exclusively pump for them. Yes, your milk will come in just by pumping every couple hours as soon as he is born. Make sure you give him every drop of it at first as that is the colostrom. I would talk to a La Leche rep, they are the professionals and might be able to recommend something else to make nursing him work. If not, pumping can be relatively easy. I would recommend getting a double pump, just to save you that much time. I didn't need a hospital grade one, just got one from Wal-Mart but I have heard a lot of women say they are faster. You get to do it on your time, not the baby's time. You can do it more or less often to increase/decrease your supply. You can do marathon sessions if you see your supply decreasing, whereas with baby you can't make them eat every hour if they are not hungry. And, one of the best perks, Dad can take the middle of the night feedings!! lol
However, if you choose to go with formula, please don't beat yourself up! Mothers have an unlimited supply of guilt. We feel guilty over so many things concerning our children that feeling guilty over not breastfeeding him should not enter into your thoughts. Formula will certainly give him all the nutrients he needs and if it makes it easier on you and him, then by all means go for it!
Best of luck and congrats on the new addition to your family!
