Ah, poor you - but this is pretty normal. Will she sleep in a sling? You could try warming the moses basket with a hot water bottle (take it out before she goes in though!) as well. I'd try the sling first though.
Please don't sit on the sofa and sleep with your baby in your arms. Lying down together on your bed with your body turned towards her with your top leg over the other is safer, less likely to roll onto her. Sling is a good suggestion. My DS didn't like it until 4 months old. I used to go out for a lot of walks in the pram or go on errands in the car, they always worked - still do at nearly 9 months!
