the courts need a thumping for allowing this poor boy to stay with his mum even when she is just dumping him on friends and he doens't wnat to be there. would a urologist/paed or gp give a statement to the courts about the problems the inconsistency is causing?

if he is waking and just deciding not to go - could you insist that not only he change the sheets, but wash them himself as well and that he has to do it right then and there so he doens't jus get to avoid leaving his bed? sorry if that sounds too harsh - I've got no other ideas.

kudos to you for plugging on.
