Early morning freak out

EARLY this morning - like FIVE A.M! - I woke up from a deep sleep - startled.
I lay there for 1/2 a second and glanced over where Olivia sleeps and she WASN'T THERE!!!
I looked next to me and Sophie was there and Adam. I looked at the foot of the bed -because she has been known to roll around - and no sign of Olivia. I looked beside the bed and on the floor thinking maybe she had rolled off (even though we have rails) -- NO OLIVIA!!! I was FREAKING OUT!!
At this point, I woke up Adam and said "WHERE is Olivia!?!" He looked around for a bit and then he jumped up and we both went in different directions. I went through the kitchen and to the living room cause that is the route she takes when she wakes up from her nap. He went to the playroom. NO Olivia!

We then both went to Sophie and Emme's room and piled up in the bed was Emme - laying where Sophie sleeps and propped right up there in the very middle like the queen of Sheba was OLIVIA!! She had several pillows about her head and body and was just sound asleep.

*sigh*

That little NERD had obviously woken up and gone in there and crawled in the bed with Sophie and Emme cause Sophie said that when she woke up - Olivia was in the bed with them and so she came in there with us!! So, who KNOWS how long she had been in there! That is scary enough that I wouldn't hear or feel anything, you know? Ugh!!! Talk about panic attack.

Someone - HELP ME FIGURE THIS CHILD OUT!!!!!! She is only 16 months old!! WHAT am I gonna do!?!?!?
