...and they all rolled over and one fell off...

I woke up around 3 am to a thud and what sounded like Meredith running across her room. Then she cried out. When I got in there she was sitting up in her bed and relatively calmly told me, "I fell out and was on the floor!" She laid back down and I rubbed her back; within seconds she was back asleep. Wish I could bounce back that easily... I was awake for the next hour and a half!
