Acid reflux

Dominika• • 3rd of June 2015<3
I got medicine from the doctors and it's no helping my baby. She's on that medicine for about 2-3 weeks now, I went to the doctor today again and he told me to keep on going with the medicine. Is there anyway I can help my baby..anything I can do or buy that will actually work???? She is 4 months old. I'm desperate for help/advice
