Just for the sake of argument ... my daughter is 3 years old, and she often says some outlandish stuff that isn't true. So and so hit me (it didn't happen). Or whatever. In one case my daughter had a scrape on her head from an encounter with the edge of her crib, and she said her mom's boyfriend did it. But later she said it was the crib. My point is only that not everything a toddler says should be believed completely. I understand there is other evidence, but a lot of it is circumstantial or hearsay, or based on statements made by somebody else who might also have a reason to be dishonest. A DNA test, administered by qualified professionals and using solid chain-of-custody practices, would be a lot more reliable than any other evidence that I have seen mentioned yet.
