Cloudy PLEASE stop doing CC with a 9 week old refluxy baby..... I understand how tough and soul destroying the sleep deprivation is believe me (you only have to look up my old threads....my DD suffers with silent reflux and cmpi) but leaving a newborn baby who is IN PAIN to cry is cruel.
You seem to have completely unrealistic expectations about a newborn baby....and perhaps the fog of sleep deprivation is stopping you from seeing the obvious:
....couldn't bare to hear dd cry, and would go in and pick her up everytime....but she learned that if she makes enough noise, I would go and pick her up! of course she did! Babies cry to ensure their survival! They are supposed to learn this, it is normal and necessary!
She wasn't hungry, nappy was dry and empty, her temperature was fine, so I plopped her dummy in and left. Cue the full on horror film screaming! Just to make sure I wasn't missing something, I picked her up, and she instantly fell silent. you are missing something, she stopped crying when you picked her up because she wanted YOU!
And guess what? She's still screaming her head off now. Every time I think "oh maybe there is actually something wrong" and pick her up, she falls silent. I tried letting her sleep on my chest, but she is trying to lift her head up and look around - eyes red, she's yawning and rubbing her ears, she just won't give up the ghost!! It's as if she's scared she will miss something if she goes to sleep! yes, she is probably scared to go to sleep because she is scared she will be left again....
I don't want to labour the point or pile on the guilt....you have my full sympathy, the first 3-4 months with a refluxy baby are HELL!!!! But you will survive. Please read this thread, I've given lots of advice on reflux, as have others, so I'm not going to type it all out again....but please get some support (and I can't understand why your sleep consultant didn't say: you won't get the sleeping sorted until the reflux is under control?!)
