Brummie - thanks - but in our case, Nicholas like putting pieces of it on the wall & doing "art projects" with it - horrible!!!! Thankfully through the behavior modification techniques we have been able to at least "urine train" him & have gotten him to the point with the bm's to poop on the floor in the bathroom & then notify us when he has done so. This in of itself has been a wonderful blessing!.
You work with adults with Autism - wow - I have often thought of starting a "group home" for adults, so that when my Nicholas is older he will always have a home....if you wouldn't mind, as I know after done with work most like to leave it behind them, but if you could find the time to email me & give me a little information of the type of environment you work at, I'd appreciate it.
