If your children are disobedient, they should be corrected. Before correcting them, go by yourself, and ask the Lord to soften and subdue the hearts of your children and to give you wisdom in dealing with them. Never in a single instance have I known this method to fail. You cannot make a child understand spiritual things when the heart [the parent's heart] is stirred with passion. CCh 197.2
You should correct your children in love. Do not let them have their own way until you get angry, and then punish them. Such correction only helps on the evil, instead of remedying it. CCh 197.3
To manifest passion toward an erring child is to increase the evil. It arouses the worst passions of the child and leads him to feel that you do not care for him. He reasons with himself that you could not treat him so if you cared. CCh 197.4
And think you that God takes no cognizance of the way in which these children are corrected? He knows, and He knows also what might be the blessed results if the work of correction were done in a way to win rather than to repel.303Child Guidance, 244, 245 CCh 197.5
