Years ago my wife and I had a 3 year old foster daughter. We took her to a park one day and she walked in front of another kid on a swing and got kicked in the chin causing her to bite her tongue.
Not a terribly serious injury but she just wouldn't stop bleeding. We took her to the emergency room and I was holding her, we were both covered with blood and it looked terrible. She was calm by then and the nurses wanted me to step out of the room. I knew the purpose of that, they wanted to ask her if the big bad man had abused her.
They had to call it quits in that effort because every time I got out of her sight she wouldn't stop screaming for me and they were unable to question her because of it.
I did follow up on it and found out the girl had been with some group of kids in a car and had evidently wandered off a couple hours earlier when the rest went up to a door, along with the chaperone. Then, they drove off without realizing the girl had fled and couldn't find her when they went back soon thereafter.
As for when she was up on my deck, she pretty much cried the whole time so all I got out of her was that she was alone and lost, which was easy enough to see anyhow, not that I cared to ask many questions to begin with. I just wanted it to go away with minimal drama. :)
PS. I really do like kids; I'm just not stupid..
When my daughter was 2-1/2, many years ago, she fell and hit her cheek on a coffee table at her aunt's house. Tears and a suppy lip, but just a little redness. The next morning, when we went to her room to get her up, she had horrible swelling of her left eye. Swollen shut, to be exact. With a low grade fever. We rushed her to the hospital. En route, her temp soared and she had a febrile seizure while being admitted. Scared the dickens out of us.
Her pediatrician, at the time, made "comments" to us, letting us know she'd have to let Children's' Services know about the situation. Shocked us both to the point of speechlessness. As it turns out, she'd been having ear infections. As back luck would have it, the knock on the noggin allowed some of the 'bug' to travel from the ear to the sinuses behind the left eye, causing the swelling, fever and nasty looks.
We "fired" her pediatrician and told her she'd better never approach either of us, or our daughter, lest she be sued for everything she owned, or ever would own.
