The psudeo images may not be actual children but cartoon charcters or similar in a sexually explicit way. Not sure but i have come across charges for that in my work before.
I will just echo what others have said regarding documenting any changes you may notice in your daughter strange things she may have said. in saying that if you start looking too hard for anything you will always find something so just be observant as you would as a normal parent if that makes sense. I know here there is a special training for people especially for interviewing children in this situation and all the police i have ever worked with have been wonderful at questioning but not making a child feel uncomfortable.
I am sorry you and your daughter are even in this situation
So sorry your going through this. Thoughts and prayers to you all.
