Does anyone know what you should do if you think your baby has it? I don't think my HV believes in it... And those posts have just described our lo to a T. She makes a funny noise that sounds like she has acid in her throat and it hurts, and she also vomits between, during and after feeds. Not possiting. She also doesn't settle too well, seems to be hungry as she has just thrown up half her boob / bottle milk. But it will take her all day to eat, fussing etc. And it seems to be hard to wind her.
