Frankly, I'm just so terribly sorry...It is so hard to imagine that there are people so horrible who would do this to your baby. I'm so glad she has you to turn to for comfort and support and I know you will do all you can to encourage her to get counseling and be gentle with herself.
I too think time and prayers will help guide you. I also understand your son's concerns. I am praying for him too...neither of your children are to blame for this horrible crime.
Please take care of yourself Frankly and know that you and your family are in my prayers. Hugs.
