I am trying to figure out ways to discipline my son, who is a little over 2 1/2. He is a very sweet boy, but when I correct him - he is very aggressive back to me. What worked for my daughter - clearly does not work for him. When necessary - if spanking has been tried - he would hit back…. going to time out on a chair in another room worked…for awhile when he was younger but now does no good. Sending him to his room - I would have to take time out and hold the door shut because he is so upset and beating down the door. The ticket method he simply is too young for and doesn't understand. He is at the age that I need to get serious on correcting him and don't know how with his temperament. What do you recommend?
