Thanks for all of the thoughts, prayers, and well wishes. The MRI is done, the stuffing is in the oven, and we're looking forward to Thanksgiving :)
We got to the hospital a little before 7:30am, and Maya (who had not eaten or drank since 7:30pm last night) was miraculously not cranky. Dave played with her while I filled out paperwork and then we broke out his laptop and played "Signing Times" (her sign language dvd). She watched it until it was time to go in. Dave took her back while they put her under, and then we went downstairs and read in the cafe for a bit. 40 minutes later we went upstairs just as she was waking up. She whined/cried a little, but was mostly just tired. Drank a bottle, filled out another form, and we were on our way home (a little after 10).
She's been fine, slightly sleepy but really no big deal. The nurses commented that she was very easy---some kids really scream I guess.
So that's it---I'm not expecting to hear anything from the doctor before next week.
