3.9 year old with autism seems ready for potty training but won't sit on potty long enough. Is the iPotty (potty with iPad stand) a good idea for him?

Do you really want . to pair those behaviors? Once you do, transition to a regular toilet is going to be tough! Use his developmental, not chronological, age, for readiness: Can he stay dry for 2 hrs., walk from room to room, recognize the urge to go, use a word to say so (e.g., potty) & pull his pants up & down? If so, use a Little Looster stool & read " Steps to Independence" by Baker, ~$30 on Amazon.com. .
