I don't know if you addressed this or not but my son Jonathan had terrible colic and it turned out the problem was I was trying to breastfeed on a schedule. He had a little tummy and so was so hungry he was gulping in air (my nursing technique needed refining as well) and so he swallowed so much air that he was full of air and not much food--so he was hungry again really soon (and crying from the gas in his tummy). What worked for us was just taking a day in bed with him and nursing basically on demand (like hourly), burping vigorously, and just quiet calm time. Once we got through that...we went to an on-demand schedule (which made my mom NUTS--she was of the "feeding every 4 hours school") and he was nursed probably every 1.5 hours to 2 hour until he was about a month. This is particularly the case with my preemies. I didn't supplement with anything, a real earth mother that way (Laura: cue the whalesongs...). Have you learned how to swaddle? If so, there is one technique that worked like a charm with Jon. If the baby is fully tightly wrapped (arms down at the side) and then flipped over on their tummy (like you hold a football) and then rock very fast and very gently while shhhing the baby in their ear very loudly (I saw this recently in a news article too, but had been taught this when Jon was small) you will see an amazing response. I think there is a book about it now...forget the name. ANYWAY...that is what I did and it seemed to work. Good luck!!
