I'm stunned! What success! How many times did you wake up last night listening for her?
Dude, I'm pregnant. I slept through the night right along with her! But I did wake up before her at 6:15 or so... and then I looked around a bit panicked wondering where she was... I honestly think when you've gone SO long without a good long stretch of sleep, and then you get one, the ability/chance to sleep overrides the worry. Plus, I think her age makes a difference. If she had done this when she was 6 mos, I would have been awake every 2 hours to check if she was breathing... but at this point... I mostly know she's ok.
