First thing to do:
1- see if he is a deaf take him to an ears doctor.
2- if he isn't a deaf he can be in the autism spectrum.( probably it's the case)
I guess the question would be what then do you do when he goes back to doing what he was doing? Do you put him right back into timeout? And, if so, what does he do?
I do the timeout right after i say it the first time, what I am talking about is right after he comes out of timeout he goes right back to doing what it is he went to timeout for. And Rockrose, yes his father is here helping me and no his father is not like this.
If you are repeating yourself 10 to 20 times a day, then all of the discipline you say you used isn't going to be effective. If your son fails to obey you after the first time told, you need to discipline him. Repeating yourself isn't discipline and needs to be avoided. Once you begin disciplining him after the first time told, your son will begin to get the message that he needs to obey you immediately. Currently, I'm sure that he expects you to repeat yourself and therefore neglects to do as he is told. You conditioned him to behave this way. Likewise, you can easily uncondition him.
The most effective discipline for a 4 year old is a timeout. There is a clear right and wrong way to implement timeouts. If you would like for me to help you with implementing effective timeouts, please send me a message.
Is his father like this? Is his father there to help you teach him how to behave?
