Why?

I am sitting here, very tired, trying to find a source on what to look for when toilet training a down's syndrome student.  I am not finding what I am looking for and am really not having any luck whatsoever.  I am tired, I am getting a bit grumpy and agitated.  I need to step away from it and so I am doing so.  Need to just regroup and figure this out when I am not as tired.  Wanted to get this class done today but couldn't make it happen.  Hopefully tomorrow I can knock it out.
