The unyielding love parents have for their offspring:
Many of us have watched the nature documentaries showing the Animal Kingdom, specifically wild life Parenting 101. How the mother regardless of specie will protect her babies with her life. Just like human mothers, they are absolutely willing to make the ultimate sacrifice. How that mother teaches her babies the life skills needed to survive and beyond that thrive. And the best chance for them to survive ultimately will be to self-protect!!! In this case how to hunt, to sense danger, create living quarters be it a nest, den, cave, burrow etc, in a time frame that she deems necessary for them. She is preparing them for adulthood. Once she deems that the time frame has elapsed, it is time to for them to move out, go out on the own, and create their life. The mothering part of parenting is complete, the nurturing is done. From birth, she instinctively knew what she wanted for them and what they critically needed from her.
