This is the price of feminism.
The one who bore the child is the one who is responsible for it (along with dad).
I am a woman and I don't have children. But if I did have children, I would be the one taking care of them. That is your duty as the mother. If you don't watch your own, then you have no one to blame but yourself. I would defend my child with my life. Anyone who would hurt my child would do so at their own risk.
This is why traditional values matter.
