That is a curious aspect, and I think it speaks to how quickly she went off the deep-end. She's claimed to have been nannying the children for 3 or 4 years. I'm guessing she was much more well put-together 4 years ago than she is now. She also says that she had to be "in the closet" about being trans and plural at work, so she didn't expose the children or the parents that particular segment of her insanity. Still seems like the parents should have spent a little more time on that background check.
