Humpty Dumpty had a great fall

This evening Minami took a fall off the side of the sofa - she jumped on the arm rest to sit on it and fell back, hitting her head on the carpet below (next to the piano). It was a pretty loud bump so obviously I freaked out, but after a good 15 minutes of tears and screams she seamed ok. This would be the 2nd time she fell off the side of the sofa, the other time she fell off the opposite sofa arm (perhaps a year ago) and landed on a set of her wooden blocks on the ground, giving her a distinct square bruising on her face. But this time it was a straight fall onto carpet so at lease the hit was padded. I'll be keeping an eye on her but the general consensus is that if she didn't loose consciousness at any time and doesn't experience any nausea or dizziness then she should be fine. It's been an hour since she hit her head and she's playing as if nothing happened. In fact I caught her sitting on the sofa arm once again and warned her she could fall again - she promptly got down.
