What's It Going To Take?

SERIOUSLY, WHAT'S IT GOING TO TAKE FOR TAESUN TO WEAR HIS SEATBELT?????
I was trying to get Taesun to go to sleep for his nap which was much needed today after going to a normal day of school for the first time in a week. He kept on kicking/hitting me and squirming out of his bed. He WOULD NOT go down. Then, I remembered that he does well when we get in the car and take a ride. He tends to fall asleep fast this way. I put him in his 5-point harness and started to drive. Once we got out of our subdivision, he started squirming and wiggling out of his seatbelt. I thought he would stop and fall asleep so I ignored him at first. Then, as I was just gettting ready to creep up to the fire station, he got out of his harness seatbelt. I was livid!! I pulled right over and told him that we were going to talk to the policemen and firefighters about wearing your seatbelt. He couldn't believe I did that. He was shocked. I told him that we were at the jail, (a little fib every now and then won't send me to Hell, I hope.) and that if he didn't wear his seatbelt, that I was going to turn him into jail. He STILL wouldn't put on his belt. So, I did what any maniac mom at her wits end would do....
I actually went inside and asked to speak with a fireman so he could explain to my 3 year old why he needs to wear his seatbelt. They complied and sooner rather than later, we were standing in front of a fireman. He was WONDERFUL!! He told Taesun that he could get hurt really badly if he didn't wear his seatbelt. He also said that the policeman could pull mommy over and take her to jail and make her pay alot of money, because it is against the law to ride in a car without a seatbelt. He scared Taesun just enough. I made Taesun tell the fireman that he PROMISED to ALWAYS WEAR HIS SEATBELT from now on. He shook on it. Now, we'll see if it works...
Next step is to take him to jail and let him visit and talk to the policemen about seatbelt safety. No joke- I will do that. It's just that important!!
