J.P.
I went through the exact same thing. I tried Gentlease, Soy, mylicon, but nothing worked until a friend recommended switching to Good Start formula. I was highly doubtful it would work because my daughter was constantly crying from gas pains, but after about 2 days it was amazing. it costs a few dollars more than the other formulas, but definitely worth every penny. Get what you pay for I guess. Good luck.
