K.P.
I had the same problem with my son. He cried constantly for the 1st year of his life. I was told he was gassy or had on thing after another. I tried several different types of formula but never soy. When he reached his year mark I gave him regular milk and the seemed to aggravate the issue even worst so I switched him to soy milk and all his problems went away. He is now 2.5 and can have regular milk but I still give him very little just to be safe. I say switch him to soy formula & see what happens.
