Or that religion is somehow a cure for depression?

I hope, for your kid's sake, that you figure out how wrong this line of thinking is before you screw up lives and relationships with this notion.

Hopefully your kid will grow up mentally healthy (though with a parent who MUDs, what are the odds?) but if they do develop depression, please don't try to address it as a failure that can be fixed with spirituality.

At best you will merely frustrate both of you, at worst you'll drive a wedge between you.
