We had a much better night last night without the swaddle than we had the first night. Slept for 8 hours, woke to eat, and then back down for another 3. Yay!
Of course my 4 yo came into our room at 3:00 in the morning crying of a stomachache and was up for the rest of the night, so I didn't get much sleep anyway, but at least we only had to deal with 1 non-sleeper instead of 2!
Re: Night 2 with no swaddle - success!
We are using a sleep sack too. I think this weekend we'll give it a shot and see what happens. I don't want to chance it during the week. I'm already a zombie at work.
