We put the girls to bed unswaddled for the first time last night and they continued sleeping through the night just like nothing had changed. Cordelia "woke up" about 30 minutes after we put her down, but then went right back to sleep after we gave her her pacifier. She actually ended up sleeping until 9 am, after having gone to bed at midnight. I had been really worried that they'd wake themselves up a lot, but they didn't.
And the fun part is that they look so cute in their pajamas. When we were swaddling them, we just put them in onesies so they wouldn't be too hot under their swaddling blankets, and I lamented all the adorable pajamas that weren't getting worn. Now they're wearing them and I'm happy.
