My son's 8 months and I actually quit work to be with him and breastfeed. I couldn't handle pumping at work and then trying to get him to take a bottle. I figure, I have plenty of time in my life for outings with friends and nights away with the hubster. But this is the one time in his life that he really, really needs me... depends on me for his every single thing. I gotta be here.
The one and only time I left him overnight was Black Friday this past year. I left him with DH and some pumped milk. I had planned to pump, but forgot my batteries.

Man, was a full in the morning! And
of course, it was one of the few times he slept all the way through the night and didn't wake up until I got home. DH is the only one I trust to leave him with. I left him with my parents for an afternoon out with DH once and was worried the whole time (I don't know why... I'm still alive after all).
