I could figure out that she'd knocked her head into the wall - but why all the blood?
So my intentions of soothing them with going to the hospital created this traumatic moment for them that I didn't anticipate. Yes, they know she had Muscular Dystrophy and that a "disease was eating her body." But their short lives had taught them if you break open your head and you're taken to the hospital, you will die.
It's been quite a day.
