I certainly wouldnt start with Dairy as the culprit. I know there is a list somewhere of gassy producing food so you may want to check that out first...it could be something as simple as broccoli or onions, which means you would have to limit but not cut out entirely.
Also 3-12 weeks is PEAK gassy period for babies...It could just be a normal phase for your little one!
