It's a story within a story--about a boy who learns that his brain is in control of his body-that when he sleeps, his brain is still awake-that's why if he's hot at night his brain tells his legs to kick off the covers, if he hears a loud noise his brain tells him to wake up, if he gets to close to the edge of the bed, his brain lets him know to move over..and when his bladder is full his brain will know that if it's full it can stay full all night because you are in control, or if you can't hold it, your brain will wake you up and you can go to the bathroom, use the toilet and go right back to bed.
I really never thought it would work, but got the book out of the library on the off chance.
I guess it's mind over matter, but my son has been dry more often after reading that book than he has been in his entire life..and he has TRIED so hard in the past, he does not want to wet the bed.
*I* think it's because the book is incredibly boring and the kids know that if they stop wetting the bed, they can stop reading the boring book.
