The most common cause of delayed toilet training is toilet training resistance or refusal. Resistant children are older than 3 years and know how to use the potty, but elect to wet or soil themselves.
If you feel as though your 3-year-old is the last kid in her class to master the potty, you're not alone. While many kids start to show an interest in the potty at 2 years old, recent research indicates that only 40 to 60 percent of children are fully toilet trained by 36 months.
Generally, if a child is 5 and still not potty trained, the child needs to be seen by a doctor, McCarthy said.
Many children show signs of being ready for potty training between ages 18 and 24 months. However, others might not be ready until they're 3 years old. There's no rush. If you start too early, it might take longer to train your child.
Most kids who are not potty trained by the age of 6 are likely to be passing through one medical issue or the other. It is important that the parents are observant to know and proactive enough to seek medical attention at the right time.
The symptoms of ADHD can interfere with toilet training and the establishment of ongoing continence. In fact, considering a diagnosis of ADHD in a 5–year–old with toilet refusal or an older child with encopresis or daytime urinary incontinence may aid in understanding the problem and in developing a treatment plan.
Only 60 percent of children have achieved mastery of the toilet by 36 months, the study found, and 2 percent remain untrained at the age of 4 years.
Many children with autism take longer than is typical to learn how to use the toilet. This delay can stem from a variety of reasons. Many children with autism have a general developmental delay. That is, they simply learn new skills more slowly than other children do.
22 percent of children will be potty trained by the time they are two and a half years old, and that number increases to 88 percent by the time they are three and a half years old.
Often, Sensory Processing Disorder (SPD) and difficulty in potty training go together like peanut-butter and jelly. might take a little longer to toilet train depending on their sensory needs.
The average age in which a child is successfully toileting was 3.3 years of age for children with autism in comparison to 2.5 years of age for children with other developmental disabilities (Williams, Oliver, Allard, & Sears, 2003).
Ways to overcome potty training resistance. Make it your child's choice. Let him know he can switch to big boy underwear or Pull-Ups and use the potty whenever he wants to, and that you're there to help when he asks. Then give it a rest and don't talk about it for a while.
Children with ADHD may not respond as promptly to physical cues of either defecation or urination, and have difficulty interrupting current more desirable tasks. Children with ADHD may be unable to focus on defecatory urges long enough to carry out normal evacuation.
They're not ready
But sometimes, kids who appear to be potty trained for some amount of time just aren't developmentally ready to keep it up for the long haul. “Some kids will seem to regress, but it's just that it wasn't really the right time for them to be fully potty trained,” Dr. Schwartz notes.
There are many different reasons why your little one may be experiencing potty training anxiety. Maybe it's an irrational fear about being flushed down the toilet, or the flushing noise it makes is just too loud. Or perhaps they feel anxious about using a bathroom in an unfamiliar place, like anywhere but home.
But many kids beyond the age of toilet teaching (generally older than 4 years) who soil their underwear have a condition known as encopresis (en-kah-PREE-sis). They have a problem with their bowels that dulls the normal urge to go to the bathroom. So they can't control the accidents that usually follow.
