A strong-willed child can be both charming and defiant. He is very persistent and is even willing to take punishment to win. A strong-willed child is generally gifted in manipulation. In fact, he is willing to cause emotional upset if it is a means to gain control of his life…being strong-willed goes beyond being stubborn. A strong-willed child resolutely defends his position and questions any and all authority over him to determine his or her “right” to retain command. That is more than stubborn.
