I'll be thinking of her tomorrow, I hope the surgery goes well.
There is such a need for foster homes right now, you are doing a wonderful thing, but I don't need to tell you that.
I have only been fostering since August 2009, so I am a newbie at it as well, I'm sure you have LOTS of support but if you ever want to chat or have any questions I can help with let me know!
I adopted my first foster back in December! I could not let her go, I have to say one of the most rewarding things I have ever done is decide to be a foster mom.
