I am going through a similar problem, so I will give you a little tidbit I learned today. I have an almost 5 year old who was fully trained but regressed when we moved. We just moved from San Diego, CA to Raleigh back in May. Anyway, an early childhood education major who is specializing in 4-8 year olds gave me a suggestion today. She said it didn't work for the younger ones potty-training, but 4-8 year olds respond very well to instant gratification- much like puppy training. :) Give them some instant reward every time they do what they should, then as the behavior becomes more frequent begin to back off with the tangible rewards and use more verbal praise. Still give the tangibles often enough to keep them guessing and wanting. At some point, the behavior will become a habit and they won't need the reward anymore. So that is the new trick I am about to try. If you want to give it a whirl, we can trade war wounds and see how it goes... Good luck to you...
