If I have to send my kids to their room for the rest of the day for a punishment (loosing all their tickets or something like that) how do I keep them in the room? I would physically have to sit by the door or hold the door shut. If I lock it from the outside he goes ballistic and kicks it until it breaks. He is 6 by the way. I feel like I am held hostage by his behavior. His 4 yr old brother is following suit.
