poor little thing, sounds like she is having a rough time. I'm not sure about all the different formulas or medications, my DS was on medication for a while for the reflux, I just cant remember what it was called. I also used infants friend for my son and that seemed to work well.

In terms of settling we found elevating his bed/ bassinette with a towel rolled under the bed helped him get some extra sleep and keep his feeds down. For the wind I use to fill a baby bath with warm water, hold him under the arms and submerge him up to his armpits and just let him kick his lower body away in the water. I did this from about 2 months. It relaxed him and on just about every occassion he would poo,burp or blow bubbles in the water with his bottom. For a while there I was doing this several times a day in conjuction with the burping every couple of minutes of b/f etc.

have you considered going to see a child health nurse instead of a GP, or maybe another GP, or a pead?

hope you find a solution soon, sounds like you and your wife are doing a wonderful job and need some sleep.
