I had an experience with silent reflux too - a lot like what you describe. Nursing was a nightmare - screaming and squirming through every feed, waking often at night. I finally ended up in tears at her doctor's office when she was 6 months old. By the second type of med, things we so much improved, I was kicking myself for not going earlier! It's definitely worth looking into and having a chat with your doc. Silent reflux babies tend to be chubby because they don't spit up, but they nurse a lot to soothe the acid.
