That is a wimpy way of trying to get him to agree to her order. A balky child, particularly a very young child, doesn't care about explanations. He wants to do what he wants to do. But he will accept a clear-cut order, however unwillingly, with less fuss than one all cluttered up with explanations and pleas for agreement. And don't worry, your child will love you.
Young children tend to love their parents, sometimes against great odds.
But she may grow not to respect you, unless you consistently sound like you mean business when you issue an order, and then follow up on it. Parents who constantly sound as if they are pleading with a child cannot expect much in the way of either compliance or respect. None of us likes to be whined at. Most of us respond much better to good, clear-cut directions. Children do too.
