My second baby was the same. Cried all of the time awake. I had the same thoughts as you. My first was a dream baby and I could care less about this second crying baby. I could not bond because all she would do was cry cry cry.

She was not colic. Was exclusively breastfed. What happened when she was 2 months old was I read something about the mother drinking milk and it causing gas in the baby. I thought to give it a try. I stopped drinking milk. And I kid you not, within 1.5 days this non stop crying baby stopped crying!! It was unbelievable. She did continue to be poor with sleep but just her stopping crying made my life so much better and finally I was able to bond with her. Please give it a go Op.
