You could try some infants friend - I found it worked wonders for my DS when we changed to a AR formula and because he wasn't throwing up and burping from his reflux, he got a lot of lower wind pain, but he was about 3mths old, but it is safe for little babies too. It also helps with their bowels too. One thing I found made a difference too was when he looked uncomfortable in his sleep from a belly pain, I would put him on his side and it seems to make it easier for him to let it out.
