Oh, you threw her in feet? Okay, I was thinking you walked up to the bed and tossed her down, not that you chucked her clean across the room.

I'm still a bit surprised that broke ribs though - I mean, even a full-force punch specifically intended to cause injury isn't usually going to do that, typically takes a clean and strong kick at least - so I'm still wondering about a calcium or vitamin K deficiency. Consider getting vitamin tabs of those.
