This happened two nights in a row. I went into Duckie's room last night at 10:45, she had twisted herself up in her blankie and I figured I would straighten her out while she slept. She was very stiff... she was lying on back and had her knees bent. I couldn't lower her legs. She wasn't resisting me, just very rigid. I tried to move an arm and it was stiff too. It was kind of strange, usually she's all limp and easy to move. ????
