I was downstairs tending laundry when dd1 shook the playpen up on its end far enough to actually flip the baby over! I really freaked out at her. I screamed loudly, grabbed her and put her on the sofa. I told her I never wanted her near me or the baby again (I know, way too harsh, but I was so angry!) Later I talked to her in a calm voice and told her to never do that again (moving the pen with baby inside has been a daily issue for some time). DD2 was upset and crying, but seems ok, though I posted in babes about what to watch for in her.
Now, I didn't actually see it happen, and I know dd2 is working on rolling from her back to one side, but when I talked to dd1 about what happen, and she used mostly gestures, I gathered that dd1 rocked it up on its end, dd2 flipped over on her head (somersault style), possibly hit the end wall of the pen then landed on her tummy, with her head touching the end wall. She wasn't laying straight, either. Last I saw her she was on her back in the middle of the pen, but I don't recall which end she was facing when I put her in there.
I guess there are a few issues here, one being my own mishandled anger, but I am at a loss about how to get her to stop doing these sorts of things, and how I *should* have handled it, or how could I have handled it better.
I am so scared for the well-being of my dd2, I'm surprised it wasn't much worse. But I am also worried for the emotional well-being of dd1...
