Hi bubbles
My DD rolled off our bed at around the same age, and i was just as stressed. I took her to the hospital and they said if she cried that is a GREAT sign. If she didn't cry and then vomited that is a very bad sign. Our bed sounds to be higher than yours too. Oh the doc also asked if we had carpet (yes we do), and he said thats another good thing!
Hope she's feeling better, and i hope you're feeling better too
