I came across this book on the internet, it was very helpful with many things, they showed techniques for potty training. It also had information on getting an autistic child photographed and it showed natural supplements to help autistic children sleep. I had problems with all of these areas and this book was excellent. I highly recommend this book.

April, try the Dvd by seasame street on potty training...it helped me with my son ...view it over and over, then walking him to the restroom and would go back and forth to the video etc. it took a while but he finally got it... You can do IT!! Liz  

April, go to the "Library" section of this website, and scroll down to the "potty training" article. That might help you out. I'll ask some other parents on here to share info with you as well. Good luck!
