I get so tired of people offering their unsolicited advice about how my wife and I need to ensure that our children socialize with others. They have a very tight circle of friends, and that's the way it'll stay until they move out. We refuse to bow to pressure from others who let their children dress any way they want, for example, just so their little darlings engage in "socialization" with others.
I get this pressure from so-called trad family members. They don't understand that we genuinely enjoy being at home and being together without others present. We don't feel a need to socialize with others. Although we do at Resistance Masses where the other families are just as "isolated". It's just a way for worldly people to justify their lifestyle.
I believe that God created Man to be social -- to seek and need the companionship of others. One of the worst forms of torture is solitary confinement. That is also why even religious usually need the company of others -- a vocation to the eremetic (hermit) life is rare, even among religious vocations.
So it's important for Catholic parents to help their children find other like-minded children --
even if they're not perfect or exactly like your family in every way (this is important) -- so they can have some friends and socialization. If you want your children to not crave the attention and affection of worldlings, family sacrifices need to be made to this end. Devoting a whole Sunday to visiting with a family from church, for example.
It's also important to shelter your children up to a certain age. I'm talking about pure, un-apologetic, keeping your children from the world. This should be done up to a certain age. Those under 7 aren't well-formed in your family's culture, beliefs, or religion. Throwing them to the wolves to go survive "in the real world" under that age is just foolish.
However, it's equally important to not treat your 12 year old like a 7 year old. As your children get older, you need to explain the WHY of things, and not just rely continually on the argument of
authority "because I said so". You need to start weaning yourself off using that phrase with your children as they pass the age of reason. By the time they are over 10, you really should seldom have to use it.
Usually, there is a good, rational/religious reason for everything you command your children to do.
But treating your children like criminals and/or children -- when they are teenagers -- is a recipe for disaster. You almost REQUIRE them to rebel in such a case. Some parents can be very negative -- not trusting their children when they really should. Not trusting them when they have every reason to trust them, and no evidence that they shouldn't trust them. It's very sad.
