In my quest for a good nights sleep my DH and I tried a bunch of new things today:
Lots of daylight, restricting nap time to the crib instead of the swing, a bath, and we used the miracle blanket but didn't tie down his arms (which he hates).
He went down at 11pm, woke up at 1am for a feeding, down again at 2am and back up at 4am. Now he's wide awake and happily swinging away.
Considering 4 hours is more than either of us have gotten in a long time I call it a success! Plus, I feel oddly rested.
Thanks for all your advice! I'm hoping to lengthen these sleep sessions a little bit every day
