For the Record
So 5 days ago, we've started the sleep experiment. The tricky thing about sleep experiments is that not only is it not guaranteed to work, 1) it will mostly likely cause even more extreme lack of sleep, 2) it will most likely make for a lot more work and frustration in the short term, 3) the above two reasons makes it extremely difficult to stick with it for more than one bad night.
The reason I'm determined is that I think that Jack is old enough that he can really truly make it until midnight without nursing (therefore the goal is humane and not "sleep training" per se), I am starting to be so tired that I'm not being a particularly great mom during the day, and I have a partner that supports me.
Hence, I start Jack off in the crib, go to sleep on the couch downstairs, and Jonner sleeps in the basement. Before midnight, all wakings are handled by dad. Afterwards, I'm back on duty. If I can stay awake long enough, I come back down to the couch after he falls asleep.
So last night was the first breakthrough. He woke up at 10:30 as usual, but then went to sleep by himself after crying lightly only about 3 minutes. He was up again at 1:30, and again at 2:30, but then slept till 5:30 and nursed in bed till about 7:30. Still, it's progress.
I don't know if I'll really update this thread, but I just needed proof for later in case I ever forget how hard it was.
