Cindy, I think you assessment was correct, infant was starving. I think the infrequent BMs from the beginning shows that something has not been right from the start. Perhaps with increased intake via SNS, baby will be somewhat more content and mom can use pump at other times. On trick is to have baby nurse on one side and use electric pump on other. It takes an extra pair of hands tho, especially if she is already trying to keep SNS in too. I may be wrong, but I don't think colicky is the correct term. Hungry is the one that comes to mind. I would cut out ALL dairy for 2 weeks and if no change add it back. To add back - Start with yogurt and cheese 1st and fluid milk last. I would get the tincture that Pat Gima has mentioned and really use it big time. I use the 2 1/2 x baby's wt equals # of oz per day divided by 8 equals approx amt for one feeding. The metric version is in the archives. Good luck, Pat in SNJ
