I just can't think that putting a baby anywhere near a croc. could be okay. It doesn't matter how well you know animals the fact is that you can never completely predict what will happen.
Earlier I used the example of Roy Horn and his tiger. I know that he never would have imagined that happening. He probably would have even thought that he new his tigers so well that he could have brought his own child out there (don't think he has any but this is hypothetical). What if he had taken a child out there on the day of his attack. A baby would not have survived that.
It isn't that I think he is a bad father. I just think the he feels too comfortable with the animals. I would hate to see something happen to his baby because he had forgotten that they truly are "wild" animals.
