October babies' sleep

Susan
How does your 5-6 month old sleep these days? My LO has been all over the place, sometimes sleeping great and sometimes terribly. He's just gotten super mobile flipping around front to back and scooting all over his crib so now he can't sleep in anything but his PJs and he's still adjusting so he wakes up a lot. 
How does your LO do at night? Totally free? Still swaddled?
