Thanks everyone for the replies. I really appreciate all of the input! We are also huge Dr Sears fans so thanks to the poster for that link!!
Little background - I nursed my oldest DD for over a year and my younger DD for almost 2 years with very little problems. DS is another story. He had latching issues from birth so the Pediatrician (in our old town - we just moved from SC to MD) performed a lingual frenectomy to give his tongue more range of motion and that seemed to help that issue somewhat though he still leaves my nipples extremely raw after nursing.
Both of my DDs had typical gas and tummy issues. DD#2 had reflux as well. Mason has been just miserable with tummy issues. He is very gassy and Mylicon doesn't help at all. He also will go 2 days without a BM and then have 3 or 4 pure liquid diarrhea diapers in a row to clean himself out. This pattern has gone on for a couple of weeks now and the poor little guy is just miserable. His spit up has also changed and is now either a chunky texture or tan in color. Poor thing just cries and screams in pain.
I just want my son to feel better. I am a big proponent of BFing and DD#2 was an EBF baby. DD#1 did have some formula when she was jaundiced due to some bad advice from a Pediatrician who told me that I shouldnt be nursing her until the jaundice went away.

There was no pressure to supplement DS - this was my choice for convenience due to our family circumstances. I don't care to get into that debate - everyone has their own reasons for BFing or Bottle feeding. This is what works best for us. I have never been able to get much at all from pumping and certainly not enough to sustain DS.
I am lactose intolerant so I don't eat much dairy anyway but if cutting out the things I do eat in order to make DS feel better works then I am all for it! Can't hurt in helping me lose this baby weight too, right?? I had to follow a similar diet when I had my gallstone issues before I had the gallbladder removed (while 17 weeks pregnant with DS!).
I started DS on the Nutramigen and I have avoided anything dairy today - or at least the obvious things until I learn what else not to eat - and have nursed him as well. DS hates the Nutramigen (it smells horrid too!) and so far he is still having the bad tummy issues.
Poor sweet baby is finally asleep in my arms but his little tummy is still gurgling.
