Not sure why this is working but after an hour of trying to put DD to sleep and instead of blissful slumber, I just keep getting repeated wailing - won't take a bottle, won't nurse, pacifier only soothes for a little while, jostling/rocking/patting isn't working, neither is humming, swaddling is just keeping her from flailing around... etc.

Finally, out of desperation, I plunked her down in her swing and turned on the calming vibrations and the swing. For now, at least, it's making my fussy baby calm and I'm grateful. Now to see how long this lasts...
