What is inside the little head?

Baby Cola is a bit violent lately. If he asked for certain thing and I did not fulfill his request, he will just "give me FIVE" right on my face! :(

I am not happy with it. So I tried to think of way to "educate" him.

1st attempt:
Warning. I told him that it hurts and "cannot hit mummy". He thought it was fun and continued to "GIMME FIVE".

2nd attempt:
Scolding. He stared back at me, as if he was even angrier than me and "GIMME FIVE"! Grr...

3rd attempt:
Hitting + scolding. I tried to hit on his little hand, then hit on his face to let him know how it feels. But, this attempt is totally a failure. He totally lost control and hit me. Once he heard "hit", he will HIT!

4th attempt:
Putting him inside playpen as a punishment. Ok, he was unhappy and begging to get out. So, I spent the time to "lecture" him. I doubt he understands me. I let him out after I finished my "lecture". After a while, he hit on my face again. So, I put him back into the playpen. Guess what? He cried a little. Then I found him "playing" with his birdie. The next second, I heard him making the "shh shh" sound! Is that how he try to free himself by hoping to pee inside the playpen and then I will get him out of it? Too bad, the trick did not work as he had just peed. But, it certainly make me wonder is that what my 15mo+ boy had in mind?

Anyway, just in case your baby is giving you the same problem, the followings are more successful attempts.

5th attempt:
Acting. When we were alone inside the bedroom at night, he hit me. So, I tried to "pok tong cheng", I cried and told him that it is painful. At first he still think it is funny and continue to hit me. Then when this continued for a while, he started to worry. After a while, he cried. LOL!
I was quite surprised, I did not see his expression as I covered up my eyes and pretended crying. So, when I heard him crying, I quickly hugged him and "sayang" him. Then he stopped crying. *Phew* I just want to let him know that it hurts and hitting people is not fun.

6th attempt:
Distract him. Since my way of teaching him is not working, I got this idea inside my bigger head. Whenever he hit me, I will tell him to "sayang" me. It works, he will sayang me. Then when I praise him, he will be happy and forget about hitting.
