Phoebe hates being swaddled or thats what I thought, last night she screamed blue murder when I tried at first, but once she was tightly wrapped she was quite happy, and it really did help with her pesky hands!
I pat/shhd while I sat with her (from the 4S method), until she stopped moaning/crying/fussing, after 13mins she stopped and started closing her eyes, so I put her down shh/patting all the time, the recommedation is to continue till she gets past REM sleep (about 20 mins I think, certainly at first).
If you have back problems try getting a chair thats tall enough or something to help with that, I know how you feel my back isnt great!!
