cococandy: Get a good girl friend to take care of another woman's child? I assume this girlfriend will now play the role of his mother while the mother stands by the corner and stares?

The conclusion is that both parents should work something out.
One that benefits the child.
No suggestion is almighty.

However unfair as it may sound, in reality, what you are actually against happens.
