Jerejoy,
You must have missed my posting on bfg ;-)
To keep the story short, I started off with very little milk after delivering DD#1. However, I managed to breastfeed till her 3yo (started supplementing with FM when DD turns 1yo) and almost throughout my 2nd preg (had to stop in the last trimester as I was having early contractions). With DS#2, I managed to breastfeed him exclusively for up to 2yo (supply was abundant so much so that I'm feeding him, DD#1 and my friend's needy bb), no FM at all. I don't quite like fish but I took fish oil soft gel during preg.
Like I've always been telling the other preg moms, it's all in your mind. Having a positive mind is winning half the battle. Keep telling yourself you can do it and don't make the mistake of buying a spare FM at home, just in case you don't have enough breastmilk. When you have no "backup" plan, you just have to relay on your boobs ;-)
And remember, the beginning is not always smooth-sailing... trust me, it'll be TOUGH but once you overcome the first month, life will be easier for you. Good luck to you.
