Homeopathy is a wonderful science with all kinds of treatments unknown to the general population. Usually you need to evaluate the patient to get the right remedy, but it wouldn't hurt to try a few common ones just for the chance that they might work. You could try Chamomilla, Nux vomica or Cypripedium. I would try them at 30K potency, or if that is not available, 7CH. For an infant, use 2 granules dissolved in a little water, and put into the mouth for absorption in the mouth, not swallowing. Administer it a little before bedtime. If you try it for a couple of weeks and have no effect, then it is the wrong remedy and try another.
Also, if your baby was term and had no physical development problems to explain the reflux, you need to watch her diet. She is probably acidic because of the foods she eats. Carbs, milk, cereal, meats cause acidity. Vegetables offset it. She needs more vegetables in her diet, and less of the acidifying foods. Also, she could probably use the good bacteria, HMF.
