My DH doesn't wear a seatbelt and it drives me crazy! We have a mini van so I know if there is an accident he becomes a human missile...I've tried telling him over and over again, yet it does no good. Maybe I'll make him read these posts. With my kids they were never allowed to be unbelted in the car...that rule applies to this day. One trip my oldest DD (maybe 7-8 at the time) refused to put her belt back on..I pulled off the road and refused to move until she did. It took about 15 minutes of sitting there but she finally realized she was not going to win and put the belt on.
