6weeks - fussy - need help.

Tiffany
Baby FINALLY asleep after being up/restless/fussy for three hours. Tried everything. She finally passed out after I wrapped her up and laid her belly down over my knees in the rocking chair. Now I'm afraid to move her. I know she's tired! Any one have any tips on getting a better sleep? She's only calm with mommy. She doesn't seem to like swaddling and sleeps in a rock and play with blankets under her to make her more flat. She seems to sleep well in bed with me but I don't want to cosleep. Thoughts?
