Hi PP, this does sound like reflux to me.
Are you breast or bottle feeding?

If bottle feeding try Karicare Thickener from chemists, my DD gets reflux bad she was on a reflux medication and also half thickened EBM.

If you are breastfeeding bubs might have an intolerance to something you are eating? I found that DD got the symptons you listed when I ate Broccoli, I started to eliminate things from my diet to see it if was something that I was eating that was giving her such bad wind pains and it was broccoli.

Some people like it others don't but have you tried gripe water or another brand of wind drops? Gripe water works well for my DD - your bubs might be too young for this yet, I think you can start using from 1 month of age.

I suggest going to your doctor they may be able to confirm for you.

Deanne.
