Only a couple of days ago my 3 week old doesn't want to be put down to sleep. Usually she can either sleep on her own or being put to sleep by us, and put her down in her cot and she'll sleep.
Yesterday was horrible. She just won't continue to sleep if she's not on me or anyone of us. Co-sleep doesn't work either. We tried waited til she's in deep sleep before putting her down but that doesn't work either. She gets very noisy (grunting, grumbling) when she's put down which eventually turns out to a cry. It makes our nights unbearable. We tried every settling technique we know of (swaddling, rocking, soothing, etc etc)
What can I do? Is this a phase? Will she grow out of it? Help!
