I think what you need to do is do what your doing. Let them be in their underware during the day and diapers at night and nap. Every Hour take them to the potty. Let them set and than get up and leave. After a while they will realize they can do it themsleves on their own and they will. They don't know at first how uncomfertable it is. but they will. I hate training pants they don't work. When some parents get training done it's not becuase of the pants it's because the kids train themselves becuase they just get too old...
