Crib Help

aah1013

I'd like to transition DD to her crib sometime soon. She has been sleeping in a rnp, so she's nice and snug. She's never been swaddled since she's been home from the hospital. We tried to put her in her crib about two weeks ago, but she kept shaking herself awake and needing to be put to sleep again. It's like the startle shake. I tried swaddling her and she flipped when she couldn't get her hands in her mouth. After six hours of trying, I just brought her back into our room.
She's now sleeping about 10 hours straight and I'd really like to make the transition now so DH and I can have some quiet/alone time in the evenings. Does anyone have any suggestions to keep her asleep in her crib? Anyway other than swaddling to keep her from shaking herself awake? I appreciate any and all suggestions!
