We’re in the process of transitioning our 12 week old out of the swaddle. She currently sleeps with one arm in & one arm out. It’s been about 10 days & she sleeps GREAT like this. I’ve tried wrapping her chest with a blanket with her arms out, using a sleep sack, just pajamas & I’m finding it impossible to set her down to sleep with her arms out. She’ll fall asleep in my arms but her arms with always wake her up. She’s started rolling so I know I need to ditch the swaddle but how do I get her to sleep without it? Is there any technique for keeping her arms from waking her up the second I set her down?
