Thanks so much everyone.

SJ - thanks so much hun, that is very similar to what the lady on nurse on call said but they said 2 hours ! As if Im not going to watch her ALL DAY!!!! Heehee! She really does seem to be fine - running around laughing and playing. They told me to wake her after an hour of her nap - I went in after 20 mins and she stirred and then I went in again after 40 mins and she looked at me and went back to sleep! Once she was awake she was her normal self again. Thanks again everyone - it is just so hard to not blame yourself with stuff like this.
