I think chirlren in a family with strict rules grow up opposite and with rebellious spirts. Parents shall not preatch too much, especailly Catholic doctines. Only a good example can serve as the best sermon. Parents shall love each other, the wife and the husband, serve each other well, love one and only till the end. Parents go mass every week, no matter children would company or not. Children grow up with belief, and would believe in what they see in parents.
