Trying new sleeping positions

We try all day whenever Callie is sleeping to put her down. It doesn't usually last long but we are going to keep trying. I tried in the rock n play (lasted nearly an hour with constant rocking) and swaddled on her side in the bassinet (20 min max). None of these is a promising nighttime solution. Last night she was up 2 hours crying for no reason and fussy the rest of the night AND up early :(
Best sleeping solution is in the baby wrap while I walk around. Too bad I don't sleep walk.
The new natural rubber pacifier arrived today too and it's better than the rest but still she doesn't like it much. She did suck on it for 15 min and doesn't scream when it's put in her mouth do maybe she will get better with it.
