I have very strict rules regarding marriage, which means that if a child is born, it must be in a complete family.

Where the parents may not even love each other, and the child may have been an accident. A healthy environment, you know.

in which the father is able to support the family on his own while the mother takes care of the children

I don't know where you got the idea that he "can support the family." Besides, the mother can also work (and probably will), which means the child suffers from a lack of parental attention and is raised by a nanny.

and they are all in good health, both physically and mentally

Lol.
