She throws an object at one of your other children. It hits the eye. Your child is blinded in that eye, either permanently or needs treatment for years and is left with a scarred cornea for life.

I think a bit of screaming in a time out is the way to go, just to avoid a serious injury. I know DH uses time outs for a lot less and he starts the timer once the screaming stops "so Liebling doesn't think he gets out of it by screaming". I'm not a big fan of that, but by the same token I have had a nasty eye injury from DS (from a complete accident and not from throwing) and have needed surgery on my eye months later as it wasn't healing correctly. And have a huge scar on my cornea. I'm a lot stricter about not throwing things now!

With a lot of love as well as some harsh consequences for her actions, she won't feel unloved or be scarred for life. Sometimes they are just too dangerous for their own good!
