If you would just listen in the first place

Nothing says more about discipline than this. Now I would never really take my child and drive down the road at fearful speeds to get him to obey me. But there is a satisfaction to be able to let your child know that you are the parent and they are the child. In life they will learn many things and maybe one day be a great leader. In the meantime Mom and Dad are in charge. So shape up or ship out.

All that said, I don't have children, but I know when I do. I will buy a stroller for 2 and when the child acts up, I will let them know they were a twin and their sibling didn't listen.

Enjoy life.
