Reinforcing the positive and sometimes ignoring the minor stuff. We all love praise...children included. Build his self esteem by letting him so simple jobs to help you and give praise appropriately. Temper tantrum need to be ignored...give the child attention while misbehaving, and that child will repeat that behavior over and over. My pediatrician told me once that a child who is beating his head on the floor in a fit will stop when it hurts...or holds his breath until he passes out, will be so scared, wont' do it again. Remember, toddlers are searching for independence because he has learned he is a separate being from you and dad...you must set the example for the behavior you want him to imitate...be consistent and you and your husband must agree on how to handle problems.  Anger is not allowed ...step outside and scream your head off, but come back in cool and calm and address the issue.
Time out is ineffective after 5 minutes for a toddler...if that time out is in his room with all his toys...wow, what a great timeout for being unruly!!! If timeout is something that you chose to use, talk to the child after the timeout and talk about he behavior you didn't like and always remember to make it clear....you love him but not his behavior. Good luck!!!

I've found the "naughty chair" to be very effective, 2 minutes for 2 years old, set a timer.  I don't yell (even if I REALLY want to), it just makes everything worse.  Get down on your knees, so you're eye-to-eye, speak in a low tone, and tell him that his behavior is naughty and that means he has to go to the naughty chair (we have a child-size step-stool).  If he won't stay, set him back down and start the time over, as many times as it takes to get him to obey you (I know, it can be exhausting, but it will pay off, I promise). When the time is up, get down in front of him and tell him you love him and expect him to obey, then ask for an appology and a hug.  I think the most important thing is to keep your cool and stay consistent, no matter how you discipline.  He will respect you for setting bounderies and staying consistent.  Remember, he's only been on this earth for 2 years, and he has a lot to learn, and you're the teacher.

What i would do is don't give him any thing when he ask for don't give him No candy when he ask for it some kids need to know that when the mom says no that means no and if he throw a fit make him go to sleep or let him go play out side and let him get some fresh air and if you need any more ideas my E-mail is anthonynorwood77@hotmail.com or anthonynorwood77@yahoo.com
