I'm sorry that you are having such a tough time with your LO. My 4th daughter who just turned one seemed to have the same feeding problems and we tried everything 5 different formulas, chiro, losec, infants friend and infacol. The goats formula was the only formula she could tolerate in the end, she would get all bound up by the others. But now after all that drama it turned out she actually had constant throat infections the whole time which they kept saying she had a red throat from her reflux and is getting her tonsils out next month at 13 months old
Also if you are having trouble getting the losec into her then take the script to the compounding chemist and they can make up a liquid version for you.
