That sounds like a total nightmare, you poor thing!
My DD was a bit like this when she was little, I just kept her on boob 24/7. She wouldn't scream, but was just always cranky and fussy.
In hindsight, I think she was just hungry and wanting to boost my supply, so I guess I did the right thing.
Are you sure your bub isn't genuinely hungry? You're right that sometimes it makes it worse, especially with reflux babies.
These first few weeks will go by so fast, and before you know it, this little phase will be over.
Good luck you poor darl, sounds really tough.
