Without question, the most stressful years for parents are when their children are between 13 and 20. With young children, control seems to be quite easy. If a child doesn’t do what he is told to do, he is just made to do it. If a child is leaving the house and doesn’t listen when the parent calls him back, the parent simply goes after the child picks him up and brings him back. But as the child grows older and bigger, parents can’t do that any more. They can’t just pick the child up and bring him back. With older children, control is best achieved when the parents do those things the children want. In this way, the things do the controlling for you. For example, parents may think it is necessary for the child to clean his own room, but the child may think it’s no use and refuses to clean his room. It is important for parents to understand how their use of control must change as their children grow older.
