Heya, Benjamin has silent reflux and its been awful. He was given a prescription for ranitidine last week, but I didn't fill it due to DH not wanting him in meds. I'm glad I didn't because he just started to turn a corner and improve in the last few days. A few things we do in case they might help you: He sleeps in my arms. He lays in the crux of my arm with his head slightly raised and he just sleeps that way. I think it helps his tummy, he also sleeps on his side (usually the left side) this way, facing me and he seems to like that. I know when I have heartburn sleeping on my side feels good. Also, we started using a pacifier. When I had heartburn and reflux during pregnancy my body made a lot more saliva because saliva neutralizes stomach acid. The pacifier stimulates his salivary glands and he swallows more spit, it seems to help when I can see he is feeling bad due to the reflux. We also do probiotics, in case it helps, although I have no idea if its made any difference.
I sooo hope this gets better for you soon, I know its pure misery.
