I am so sorry, I was hoping she would have worn herself out by now. Poor thing - she probably doesn't understand anything that is happening right now. Does she have the opportunity to talk to or visit her mom?
She must be so scared and confused. Fortunately, you have her now and can help her feel safe again.
My father started abusing me when I was 5. I wish I could remember what I wanted/needed at that time so I could offer some insight.
