Does anyone have anything they'd like to share? I've heard advice from my friends who all have children without special needs, but none of it applies to us. Frankly, it's getting annoying. We're trying to have a third child and would like to potty train our son (on the spectrum) as gentle and easy as possible. So here's what we HAVE done:
We bought two types of potties. A floor potty (frog one that he was interested in) and an Elmo potty seat that sits on the big potty w/ step stool. We have been trying for about 9 months now to spark some sort of potty interest to no avail. I would ask him from time to time and try to make the potty seem fun and interesting, but considering we have serious delays in receptive/expressive communication... things like "big boys go on the potty" and "diapers are for babies" don't work because he lacks the ability to even understand what a big boy is.
We also bought him a watch called Potty Watch that you can set a timer for as a reminder that they should sit on the potty. Well, all of the sudden he has had interest and thinks the potty is totally cool, however, still has no idea what its for other than "wow putting this lid up and down is AWESOME and watching the water flush is pretty cool too." He also enjoys ripping off toilet paper square by square and ripping it to shreds. I will usually let him play with the toilet paper while he is sitting there otherwise he gets bored and won't stay seated. Books and whatnot don't really capture his attention because he is hyperlexic and will memorize or point out letters and numbers that are his favorite, so he's not really paying attention. The Potty Watch lights up and sings a song every 30 minutes as a reminder, but we haven't had much success. He is still have constant accidents and doesn't really seem to understand the feeling/urge of poop/pee. We put him straight in undies and just go with the flow. I was hoping that the first time he really went that he'd hear it and get excited or realize what had happened but to my surprise he didn't even know what he did. 
I always get really hardcore about PLing then give up and decide that he's not ready and I just need to go at his own pace. He's had a lot more interest lately but just doesn't seem to GET that he's there for toileting, not shredding toilet paper.
So any tips or advice that worked for your child with ASD/sensory issues/speech delay?
He is verbal, but is lacking in expressive and receptive communication.










oh well. Every time I start looking at bigger diapers I feel like I'm giving up. But like many of you say... I just don't think he "GETS" it. It's so hard to explain this to a parent of a typically developing child. Which I have one, and he PLed in like a week.
