Obviously you can't watch your children all the time to keep them safe from sins and Satan's lies. They have to go to school.
But there is options depending on where you live. You can send them to a private Christian school or a publicly funded Catholic school, whichever is best.
Be forewarned however that Catholic girls can be evil temptresses and you must advice your young boys to stay clear of these evil succubi. Britney Spears once masqueraded as a Catholic school girl but now is nothing but a singing prostitute who flashes her vagina at the public, has children out of wedlock and snorts cocaine. Such women are vane about their appearance and need to be avoided for their hives of evil and sin.
If a private Christian school is unavailable you could also consider homeschooling your children. This will give your wife something to do and will crush any dreams she has of having a career.
Homeschooling is arguably the best option as it allows your children to be taught full year around and can be taught at a faster pace because you don't have to teach them nonsense like bogus science and evolutionary theory or anything about other religions that worship false gods.
Private Christian schools are great options as they also don't teach evolution and bogus science. Find one where the women teachers are good and modest and ask other parents for their opinion of the school and the sanctity of their teachers.
You will also want to make certain they aren't teaching things like condom use, which is a tool of the devil and used only by harlots and prostitutes.
You will also want to ask whether the school is active in expelling homosexuals. You don't want any homo kids in the same classes of your children.
When true Christians band together we can raise a community of good god-fearing children who will obey the will of the Lord God.
