I've read over and over that when a child shows interest in the potty or discomfort at having a wet or dirty diaper, it's time to potty-train. As Quinn hasn't been in daycare where he needed to be potty trained, I really haven't worried about, figuring I'd wait for his cue.
But now that I'm learning about Sensory Processing Disorder, I'm realizing that cue may never come. He is PERFECTLY happy to spend the entire day in a wet diaper if I let him. He never complains about the feel, smell, whatever - in fact, he doesn't even seem to notice.
I got a little bench potty a few months ago, and while he loves to drag it all over the house and use it to step up to things he's not supposed to reach, he dislikes sitting on it. So I got him a potty seat that goes on top of the regular toilet seat. That he likes. He drags his potty bench over to it, steps up to sit on the potty and has a lovely time opening the little cubby door next to the toilet, unrolling the toilet paper, asking me to identify the fall foilage on the potpourri envelope. After a while he puts the potpourri back, closes the cubby door and says very cheerfully, "All done potty!" Then he hops down. NOT ONCE has he done anything in the toilet - and it's the same story at school, where he's taken to the potty each morning.
I'd love to hear any ideas, or things that worked for you!!
