Who takes care of a child is ultimately the parent’s decision and sometimes there a no relatives who can stay home with them or they might be unfit to do so.
That’s unfortunate. But people do the best they can.
What gender a child’s parents have does not matter whether a child develops and thrive, it’s how the parents behave that matters.
Not really. Girls grow into women naturally. Boys have to be taught how to be men. Women can’t do that.
