C.,
I was wondering if the behavior is aggressive or just regular toddler things. I have learned through parent classes that if you can ingnore the bad behavior and focus on the good behavior (ie, he picked his toys, or he was playing quietly ets) you will see the bad behavior disappear. What i mean is if you see him being good then you praise that behavior, and if he is acting badly try to ingore it, that is as long it isnt dangerous or aggressive. When i mean dont pay attention to him and his behavior it means no eye contact, (i keep watch from the cornner of my eye but i dont let my kids see me) no talking to him etc. Once he realizes that you are not paying attention he will stop. It wont happen overnight but it does work, take it from someone who has tryed it and succeed. Another thing you mentioned is time outs. When you put him in time out it is the same rule as before. You dont pay attention to, or talk to him. If he kicks and screams dont pay any attention to it, and when he has been quiet for 2 minutes then you let him out and then the time out is finished. Oh i almost forgot to mention for the time outs dont make them in his room, have a desingated spot for time outs, that way he dont associate time outs with his room. Could you email me and let me know what you think. IT WONT HAPPEN OVERNIGHT BUT I CAN AND WILL HAPPEN.
