Theres a difference between yelling and using a stern voice to let your kido know your serious. My SO said not to get so mad and "yell" because he uses a sweet laughter voice when telling Mowgli no- so of course he thinks its a game and does the same thing over again because to him its funny- of course I'm going to act serious when telling him not to climb out of his highchair as soon as my hands are full- duh- its not a game-its dangerous -_-
