Would you charge more for a child over 3 and in diapers still!

Well said Playfelt.

Like Playfelt said, if you can afford to loose the income on this child, then charge them the extra and see what happens - doesn't hurt to try?! I would also have a sheet of how to train the child for the parents/grandparents.

Good luck! And let us know how it goes!

hmmm...I wouldn't have much patience with that either. I think he goes in his Pull-Ups because he's being allowed to. He can, so why not? Before charging more, I would personally say I don't care what goes on at home, but in my house, at 3 we wear underwear. He walks in the door and changes. It's not as fun to wet underwear. Maybe at first, no pants, too.....it's seems to remind them more not to do it. Might be a tough week, but maybe it would work. Short time pain for long term gain. A Pull-Up is a glorified diaper and gives permission to use it as oppose to using the toilet.
I know you get into the dilemma that you're training him with no help from the parents, which is extremely frustrating, but you'll benefit in the end.
That would be my approach. I've done this and the parents see that hey, they can use a potty. Cool! DUH! Again, it sucks that they don't step up, but you gotta do what you gotta do...
