5 Year Old Autistic Boy Not Potty Trained. My son is 5 years old and not potty trained completely. I have been working with my 3.5 year old son on potty training off and on for several months now.

These signs, while appropriate for typical children, may be irrelevant to a child with autism. She has her moments and uses the potty to urinate quite frequently, but she almost always has bowel movements in her pants. Though the child might understood the importance of using a potty, he may soon tend to forget as is the case with many young children who are learning something new.
