My daughter Natalie was doing the same thing when she was little... here is was what we tried. Started with Lipil, went to soy and she was having TERRIBLE stools and they moved us to Nutramigen as well. It took a little bit of time and we added a little bit of rice so she stopped spitting up. We also switched bottles (make sure the holes are not to big) we bought a bottle cleaner to make sure nothing was being left in them. Good luck!
