Yes, yes. You know everything. We've been down this road before. Maybe I just had the one odd baby in the whole world but please believe me, there was no CIO, bedtime routine, or drug that would make that child sleep through the night. Rocking all night, walking the floors, nothing. She. Did. Not. Sleep.
I know it's REALLY hard to believe, but there are things outside of your experience and they are still true things.
