Lucy, Ranitidine or Zantac reduces the acid in the stomach.It has been approved for use with infants from one month of age and comes in many forms because it is used from infants to geriatrics. Your daughter might prefer the dissolving tab that melts in your mouth or mixed with a small amount of water to give in a medicine syringe. I could do a ad for FlavorX, available at the pharmacy. The pharmacist can use a huge variety of flavors to mask the taste of the medicine. children love it and many adults use it too. FlavorX was created by a dad for his daughter who had to take yucky tasting seizure medicine every day. The company even has a home kit so you can flavor over the counter medicine too. Take a peek at my blogs about getting a baby to take medicine. I have done more than my fair share of baby wrestling to get the medicine in. It is not fun. Jan Gambino The Reflux Mom
