I don't intend to hover over my kids forever. But, at the ages that this "doctor's" victims were, there was no need for these particular children to be unsupervised.
When my kids are with me, they are rarely out of my sight...however, my three year old goes to school half days. He is as well protected as I can make him, but the chance is still there that something can happen. My son is already used to the procedure, he comes in the door, and we talk, right then, while the whole day is fresh in his mind. At this point, that's the best I can do. I could homeschool, but I feel that it is important for my kids to have a life seperate from me and their dad. School is a big part of that. My 6 year old lives in a dual household situation. She spends a lot of time at home, and a lesser amount of time with her father's family. She wanted to live with her dad part time and us part time, but that is where I drew the line. I know she wants to know her father, but he isn't safe to be alone with a 6 year old (not a sexual issue, just a very immature man). So, instead, she lives with her aunt and uncle on that side and she is happy. On the days she isn't here, I speak to her no less than three times a day, when she gets up, when she gets home from school, right before bed. Is there a potential for abuse in this situation? Yes. But the precautions that can be taken, are taken.
I hover to a certain extent, and I likely always will. But someday they will be adults, and I won't be able to hover, even if I wanted to. Abuse happens to adults too, and I feel that it is important for them to have contact (supervised at this point) with enough people so that their internal radar is honed enough for them to understand that when they get that feeling about someone, it is normally dead on.
I think that, and a good level of self confidence, are going to do more to protect them in the long term than hovering will.
What I can't understand is very young kids being allowed alone with the doctor, or anyone for that matter. If they are too little to tell me about the course of what went on, they are too little to be alone in any situation.
That's me. I am not normal, not in parenting or anything else. But I do try to do what I feel is best. On this one, I am on the fence as to how much the parents can be blamed, as I still feel that all my kids are too young to be alone with a doctor, but that will change in time, the soonest with my oldest daughter. She is old enough and confident enough that I feel she would speak up the moment she feels uncomfortable and she would keep speaking until someone listened. At some point soon, I will have to rely on the skills I have taught her to keep her safe, in addition to my semi-hovering.
ETA: I left out half a thought, I in no way meant that I am on the fence regarding the doctor or his conduct...he is scum and someone should return him to his pond...with a gift of concrete boots.
