Carole,
I am so sorry lexie was injured. BUT, IT WAS AN ACCIDENT!!! We accidently hurt things, babies, children, pets, ourselves, ALL the time!!! Please, don't beat yourself up. Now, you will be extra careful...but, even yet, accidents do happen. If not, they would all be called PURPOSEFULS!!!

I am sure Lexie will be fine. I bet in two weeks time, everything will have been forgotten. So, give her some extra loving when she comes home, and all will be well.
