I think we are turning a corner. The past few days have had significantly less screaming. She has actually sat in the bouncy chair, laid (on her back!) on the mat and even in her bed until she's fallen asleep without screaming. This is wildly exciting.
The world feels less scary now that she tolerates being put down and can keep that pesky pacifier in her mouth. This weekend was lovely and I even got out for a walk! Yippee!
