So this happened:
Spencer is fine. Gwen is fine. Ambrosia will be fine...soon*:

Ambrosia had surgery on her leg and clavicle today at Kaiser Hospital in Oakland (feel free to visit!). She was transferred there from Santa Clara yesterday so she could be seen by Kaiser's best Bay Area bone surgeon. Within a week or so she will be back home, but due to the extent of her injuries she will need A LOT of support caring for herself and Gwen.
Spencer is doing the best he can to take care of Gwen while mommy gets better with the help of family and friends (Grandma Sandee is there this week and next; Auntie Angelique arrives on the 4th). The next 4 - 6 weeks will be a very difficult time. Please check this blog frequently for updates on Ambrosia's schedule if you are interested in helping out--while Gwen and Ambrosia's caretaking will be covered we could use a lot of help with meals, shopping, errands, and babysitting as well as moral support. Ambrosia and Spencer are both available on their cell phones if you'd like to arrange a visit.
*UPDATE 12/26: Ambrosia and Spencer were concerned that my diagram of Ambrosia's broken bones would cause a panic because it might be interpreted as if she shattered entire leg bones, when in fact the injury to her femur and tibia were just where they meet the knee. The diagram is supposed to highlight each broken bone, not where it's broken, but whatever: I replaced the original image with a more conservative one. :)
