OK Something to try that worked for my LO, who is also a refluxer with a lot of gas.
Swaddle her, and hold her close to your chest on her side faceing you, give her a paci, rock her, swing her, or even walk with her, and sing, shush, or talk quietly to her.
The swaddle and the side holding help reliease the pressure on her tummy and the Paci, rocking, and shushing sooth her.
Once she's calm lay her back down. Repeat as often as it takes for her to settle. It takes a while to fully work, it takes a lot of work and comitment.
*hugs* I know its hard but this stage doesn't last long.
Please let us know how it goes for you.
