IT does raise an interesting question. What are you teaching your son about his mother, her ability to protect and take care of herself and him, and her role in society (if a 6 year old is more powerful that she is by virtue of being male)? What're you teaching him about his own value and the value of young girls?

I don't think we need to reach the same conclusions, but I think that some degree of questioning and self-examination here is okay.
