5 mo old infant w/severe reflux

Hi! i am the mom of a GERD infant..i have read the 'Remedy Finder' which had far too many sugg's to keep straight...my baby suffers from extreme esophogeal reflux, has had it since birth, but just recently diagnosed. (she has been given rx for it, i refuse to give, but am growing weary and considering out of desperation for her) i am currently giving her Nat. Phos 6x, one pill, 3x daily diluted in breast mlk or H2O...no good (this is 2nd full day). she suffers from many symptoms, which i will list b/c it is pertinent when diagnosing for homeopathy...wheezing, vomiting (1-2x per week), spitting up (several x/day), irritability, crying, sleeping only one hour at a time, falling asleep when at the breast continually, arching back, grunting, excessive salivation/chewing on tongue, sleeps only in swing or being held, uncomfortable on back, dry cough (has contracted pneumonia and several URI's since birth b/c of aspiration into lungs), recent lack of weight gain (no loss yet, just no gain); I know that there is an effective remedy for all of this, i am so sleep-deprived (hubby is out of town frequently) i can't figure it out myself. i am well-acquainted w/herbal medicine, not homeopathy. Willing to try. Thanks so much! She is 14 lbs, just turned 5 mos., so sweet, so much in pain.
