She slept through the night!
It wasn't perfect, but K went an entire night without feeding or parental intervention (not a single bum pat). She woke up twice (9:30ish and 2am). D and I agreed we'd let her be for 15 minutes. If she was still crying after 15 minutes, we'd reassess the situation and determine how best to intervene. Well, by golly, no reassessing was necessary. She put herself back to sleep both times.
And didn't wake up for the day until 6am.
Can I get a HALLELUJAH?!?!?
I got more than seven hours of straight sleep (minus the 2am wake up, which I didn't even get out of bed for). I'm feeling better and praying HARD that tonight is another peaceful night.
