It sounds like he's very active. Do you get out of the house and give him plenty of action time? Time to run out his steam?
My method of dealing with any misbehavior when ds was younger was this:
1. Give information/instructions: Don't get into the toothpaste, I'm really upset that I have to spend time cleaning up this mess now.
2. Honor the impulse: find out what impulse was BEHIND the action. The action was not acceptable, but the impulse behind it was legitimate. Was he doing it because he was experimenting? Is he trying to get more attention? Does he like your reaction?
3. Find acceptable alternatives that honor the impulse: If its an experiment, maybe make some playdough with him. If he's trying to get attention, tell him that if he wants to play with you to come to you and say "let's play." If he likes your reaction, then start getting crazy/funny about things that are ok (Oh you better not be giving me kisses! no no no!!!)
At 3, I also asked ds to help me clean up any mess he made. If he said no, I told him that I was not happy about it, but left it at that. Afterwards, I told him that I had wanted him to clean it up but he didn't, so I had to do it myself. He cried the time I did that, and over time has been much more likely to help or do it himself.
Your child needs connection, not punishment. I'm quite certain that the punishment is making this situation worse, and not better. It's widening the gap.
Connection is the best source of discipline.
Punishment, at best, makes children behave for self centered reasons. For example: "I won't hit the dog because *I* don't want a time out" as opposed to "I won't hit the dog because she doesn't like to be hit."
It also causes them to think of it as a payment for their actions. So if dc hits the dog, and gets a time out, the hitting is "paid for" and there is no guilt left for the dc to think on. It's gone, and they are free to do it again as long as they are willing to "pay" for it again.
"We punish him by standing him in the corner, putting him in time out and sending him to his room nothing works."
Time out and it's variants are punishments that are based on separation and disconnection.
I highly recommend Becoming the Parent You Want to Be. The discipline sections give a lot of concrete information about what to do with misbehavior. It was my lifesaver when ds was younger!
