I do not know when exactly it happens but sometime between when we put Savvy down for the night and when we get her in the morning there is a lot of activity going on. We put Savvy down to sleep with her head where the blue and white monkey is in this picture:
Where I have found her the past few mornings:
I didn't get a picture as she had moved again by morning but have checked on her on the monitor and seen her with her face up against the mirror (blue on the left side of the last picture). Maybe she's keeping herself company :) Also have a short video of one of the mornings, hope to get a better one soon as she's normally VERY active and jumpy!
