She fell because she was hurrying along trying to keep up, pulling heavy luggage, and slipped on a metal ramp. She said her feet just flew out from under her and she landed hard flat on her back. I don't think she even knew she had hit her head, she just heard a loud bang. She also thought she had remained conscious and aware the whole time, when she had actually lost consciousness for at least a minute.

I wish she had gone to get checked up too, but this was in a busy street with heavy traffic, a metro and bus strike, no ambulance after 15 minutes in a foreign town (she was American), and taxis waiting just a few yards away. So I guess I understand how she just wanted to get into the calm of a hotel to rest once she actually did feel ok.

Red, must have been upsetting to handle a child screaming. That would have freaked me out a bit, it's hard to remember that "the ones that scream aren't the ones in danger", as I was once taught. You're right that she have stayed still, but I think it's natural for family to want the person to stand up and "be normal". I should have been stricter about that myself.
