The take away parenting lesson here is: don't leave your 3 week old baby on the floor alone in a house with 2 full grown huskies while you go out to smoke a cigarette. And when you've just moved into the house where the huskies live (it's their territory) it's an even worse idea.
That mother is only 17. She doesn't have the life experience to know any better (heck, she's still legally a child herself). She also probably doesn't have the life experience to cope with the mauling death of her newborn, and the guilt for her part in it.
I treated a baby once whose legal-minor parents didn't clip her car seat into the base, they just rested the car seat between the father's feet on the floor of the car. They did it for several weeks, it was less hassle, and nothing bad ever happened. Until the car rolled over in an accident, killing one parent and severely brain-damaging the baby.
We had a story here recently where 2 teen parents left their infant alone for 3 hours in a car with 2 pitbulls, assuming the pitbulls would take care of the baby while they went shopping.
The take away societal lesson here is: as a society, we MUST have outreach to very young parents to help them learn how to care for themselves and their children.
