we didnt have a special formula when my oldest daughter was little...and it wouldn't have helped...reflux she has has to do with the end of the gastric tube into the stomach not staying closed properly ( i cant remember the medical term for the body part) we found if we diluted her formula just a little extra when making it it seemed to help. she was with a gastrointenologist for 3 or 4 yrs...unfortunately when she was finally diagnosed she was older than 4 and we were told if diagnosed before then they may outgrow...so she has to watch what she eats the rest of her life. so you may want to look into seeing a gastro .
