Oh how awful and brings back memories of the start my little one had, for 2 months she was in constant pain, I was bf'ing, topping up with ebm and formula and pumping and she wouldn't take more than 500mls a day and dropped from 75 to 9th centile. I saw 5 GPs, I demanded reflux meds, 1 GP reluctantly prescribed them after telling me reflux is 'trendy'!
I honestly think they all thought I was just an anxious mother because of the death of our first daughter, which as you know is true but I knew something was wrong.
Finally the 5th GP I saw had worked in paediatrics and had treated CMPI babies and she's the first GP who suggested a dairy free diet for me (by this point I was exclusively pumping) and prescribed Aptamil Pepti for any top ups.
The difference was amazing and she's a much happier baby. My GP also referred us to an NHS dietician.
I've never tried Sophia with goats milk because I've been told by the dietician to avoid all animal milk because of the similar proteins. Soph is also Intolerent to soya.
You can buy hypoallergenic formulas Over the counter, perhaps it would be an idea to try one of those and if it helps ask for a prescription.
It really helped me to take a diary of all symptoms and also I asked my HV to observe a bottle feed to show how uncomfortable she was.
I'm sorry to have replied previously with such a short reply, I just wanted to make sure you knew that DoH don't recommend but of course you would have researched!
Its so very frustrating, I hope you get sorted x
