Potty Training a Child With Autism Who Is Older Than 5

Yes, it's still possible, and you haven't missed the window. If your autistic child is 6, 8, or 11 and still working on toileting, the steps that tend to help are checking for constipation and other medical causes, using a predictable schedule with pictures, rewarding right away, and keeping the routine the same at home and school. Waiting longer is common: in a 2017 study of 583 children with autism1, 79.3% were dry by day at age 5 and 93.5% by age 10.

What your child wears matters too. The Autism Speaks Autism Treatment Network guide advises underwear during the day so children can feel when they are wet2, with diapers or pull-ups kept for sleep and time away from home. Reusable protective underwear such as the Super Undies 3-in-1 adds protection while keeping that wetness cue. Every child is different, so adjust with your care team.

Is my older child ready? Signs to look for and what to check first

Before anything else, have a quick chat with your child's pediatrician to rule out medical hurdles, then look for a few basic skills. The Raising Children Network says autistic children generally show the same readiness signs as typically developing children, but later3. Your child might be able to:

  • Tell you, or show you with a sign or gesture, that they have wet or soiled
  • Follow a simple instruction such as "sit on the toilet"
  • Pull their pants up and down
  • Have regular, formed bowel movements
  • Stay dry for at least two hours during the day

Your child may not show every sign. Bladder and Bowel UK says there is no general agreement on what makes a child ready4, and that children with autism may never show the usual signs. That does not mean they cannot be toilet trained.

Check health first. Ask the pediatrician to rule out medical problems, especially constipation, which can get in the way. The same organization warns that handing a struggling child diapers instead of an assessment can mean conditions such as constipation or an overactive bladder go unnoticed. Ask about medications too, since some can affect continence.

Then gather a baseline. For a few typical days, record when your child drinks, wets, and has bowel movements. The Autism Speaks guide suggests tracking how long it takes between a drink and a wet diaper2 to plan toilet trips.

How old is too old? What the research says about timing

First, the reassuring part: it is not too late at 7, 10, or 12. Research shows autistic children reaching daytime dryness across a wider age range than typical models predict, and many get there after age 5.

The 2017 study of 583 children with autism compared results with a typical-development model, which expects 95% dry by day at age 5, 99% at age 10, and 100% at age 12. The autism sample reached 79.3% by age 5, 93.5% by age 10, and 94.9% by age 121. A larger share of children with autism achieved dryness between ages 5 and 10 (14% compared with 4%). About 5% were not dry by age 12, and the authors note that this can affect school placement, social inclusion, and independence.

The Autism Speaks Autism Treatment Network guide cites older research finding that children with autism needed an average of 1.6 years of toilet training to stay dry during the day2, and sometimes more than two years for bowel control. The same guide says its ideas may help young children, teenagers, and adults.

So what does this mean day to day? A longer timeline is common, progress is often gradual, and taking a break is allowed. The Raising Children Network advises that if toilet training becomes a battle with no progress, take a break and consider trying again in about three months3. It adds that this does not mean you have failed. Your child may simply not be ready yet.

Why does it take longer? Toileting leans on communication, sensory tolerance, flexibility with routine, and body awareness, all of which can work differently in autism, and stomach troubles like constipation often get in the way. A 2022 study of preschoolers found toileting resistance in 49.1% of children with autism5, versus 8.0% in the general population. None of this reflects effort or parenting.

What does a step-by-step plan look like for an older child?

Here's what a workable plan tends to look like: predictable, visual, and built in small steps. This outline draws on guidance from the Autism Speaks Autism Treatment Network, Bladder and Bowel UK, and the Raising Children Network, and it works best when your occupational therapist or behavior analyst tailors it.

  • Make the toilet comfortable. Use a seat insert and a footstool so your child is stable, with hips and knees at about 90 degrees4. If change is hard, skip the potty and start on the toilet.
  • Pick one word and build a visual schedule. Use one word for the toilet and have everyone use it. Show the steps in pictures, from pulling pants down to washing hands, and review them two to three times a day3.
  • Schedule short toilet sits. The Autism Speaks guide suggests a goal of six sits a day, starting as short as five seconds2, with one longer sit for bowel movements. Use a timer, and tell your child it is time instead of asking. Build sitting time slowly. The Raising Children Network suggests a maximum of five minutes, since longer sits can feel like punishment.
  • Reward right away, and only for toileting. Give the reward immediately after your child urinates or has a bowel movement in the toilet. Keep these rewards for toileting alone, and praise effort at every step.
  • Practice in different bathrooms. Skills learned at home may not carry over to school or public restrooms.
  • Teach a way to ask. Use a sign, a picture card, or words. As your child signals reliably, reduce reminders gradually4 so they learn to notice their own body.
  • Stay calm and keep records. If accidents follow a pattern, take your child to the toilet just before those times. If progress stalls, pause and try again later.

Put the plan in writing. The Autism Speaks guide suggests listing goals, routine, language, places, tools, and rewards so that everyone uses the same approach2.

As for the evidence, a systematic review of 26 studies found that research on autism toilet training is limited by small samples and weak study designs6. Treat any plan as a starting point and adjust it based on how your child responds.

How do sensory differences affect toileting, and what helps?

Sensory differences can turn a bathroom into a tough place, and they can change how wetness feels, too. Children vary widely, so watch what yours reacts to, because two children can need opposite things.

The bathroom. Small changes can remove barriers:

  • Dim bright lighting and turn off a loud extractor fan.
  • Put socks or slippers on a child who dislikes a cold floor.
  • Warn your child before the flush, or let them wear headphones.
  • Let your child hold a favorite object while sitting.
  • Carry a towel from home to avoid loud hand dryers in public restrooms.

These tips come from the Raising Children Network3 and Bladder and Bowel UK4.

Wetness. Some children do not notice it, and some cannot stand it.

  • Child who may not notice. The Raising Children Network suggests washable, reusable training underpants or underpants with a protective liner3 to help children become aware of feeling wet, then pointing it out in a positive way ("Your pants are wet. That means you did a wee").
  • Child who resists wearing pants. Bladder and Bowel UK notes that some children dislike the fabric, labels, or pressure of pants and prefer the firm, padded feel of a diaper. Its suggestion is to put pants under the diaper, then gradually cut parts of the diaper away, with short daily periods in pants.
  • Child who is distressed by wetness. The 2017 autism study notes that some children have acute sensitivity to clothing1, which can make changing aversive. Go slowly and ask an occupational therapist for help.

Super Undies designs its products to protect clothing while keeping the wetness cue. That suits some children and not others, so watch your child's reaction, and add protection or slow down if wetness causes distress.

What should an older child wear during toilet training?

Now for the practical question: what should your child actually wear? For daytime training, most guides favor underwear, or protective underwear that keeps the wetness cue, with disposables kept for sleep and time away from home. The Autism Speaks guide advises that during training children wear underwear during the day so they can feel when they are wet2. It adds that rubber pants or a pull-up can go over underwear if necessary, and that diapers or pull-ups may be used for sleep or time away from home. In a SPARK for Autism article, psychologist Elizabeth Cross says a diaper or pull-up can give a child permission to use it7.

Option What it does Fits when Trade-offs
Regular underwear Gives the strongest wetness cue; no protection Your child is mostly dry, or you can change often Leaks reach clothing and furniture
Underwear with a protective cover or liner Keeps the cue; adds some containment School days, short outings Extra layers to manage
Reusable protective underwear, such as the Super Undies 3-in-1 Waterproof outer layer, no stay-dry layer; 150 to 300 ml built-in absorbency by size, adjustable with liners Daytime training, and ongoing support for older children Needs laundry; bulkier than underwear
Disposable pull-ups or diapers Built to pull moisture away from skin Sleep, travel, heavier needs Less wetness cue

Two versions of the 3-in-1 fit different routines. The pull-on suits a child practicing dressing and toileting, and the quick-release version has side snaps for caregiver-assisted changes. Sizes run from Small (typical age 3 to 4) to XL (typical age 10 and up), so check the size chart and the absorbency guide.

Why is nighttime trained separately, and where do Brain Trainers fit?

Nights are their own project. Nighttime dryness develops on its own timeline, so most families work on days first and treat nights as a separate goal. Bierman Autism Centers notes that nighttime training may need to be addressed separately, and overnight dryness often takes significantly longer8. The Pants4School programme from Bladder & Bowel UK explains that night dryness is a process that develops with time and cannot be taught the way daytime dryness can9. It also says that wetting beyond age 5, after at least six months of daytime dryness, is called enuresis, a medical condition for which assessment and treatment are available.

It is common to use protection at night while daytime training continues. The Autism Speaks guide says diapers or pull-ups may be used while your child is sleeping2.

If your child is dry by day. Brain Trainers are Super Undies' nighttime sensory underwear. Super Undies says they are best for children who have been potty trained during the day for six months or more, and it calls them a learning tool rather than a quick fix. Built-in absorbency is 540 ml in Large and 620 ml in XL, and liners can add more. Super Undies reports that some children improve within days or weeks, while others need a couple of months.

If your child is not yet dry by day. The Super Undies absorbency guide says the 3-in-1 with a full-coverage liner may be enough overnight for some light to moderate nighttime wetters. Heavier wetting may need a different product, so ask your care team and contact Super Undies.

How do you keep toileting consistent at school, in therapy, and at sleepovers?

Toileting doesn't stay at home, so share one written plan with everyone who helps your child, and use the same words, pictures, and routine in every setting. The Autism Speaks guide says everyone working with your child should use the same language and the same routine2. For a child who uses the toilet at school but not at home, it suggests using the teachers' words and practicing in different bathrooms.

At school. A pediatric presentation from the Maine chapter of the American Academy of Pediatrics notes that toileting goals can be included in an IEP10. It lists staff-initiated toilet breaks, rewards, visual supports, and the school nurse as an ally. Bladder and Bowel UK adds that picture cues are needed at school and away from home4, not just at home.

On outings. Pack spare underwear and clothes, wipes, your picture cards, and a sealed bag for used items. A waterproof wet bag, such as the Kangacare wet bag Super Undies sells, keeps wet items contained. Public restrooms can be hard, so consider a family restroom and headphones for hand dryers.

At sleepovers and camps. The same presentation lists reduced peer opportunities, including sleepovers, as one consequence of delayed toileting. Plan ahead: choose discreet protection, decide privately how your child will change, and tell your child they can come to you at any hour. For a fuller plan, see the guide on bedwetting and sleepover success [link when published].

How do you protect your older child's dignity and privacy?

As children get older, this stops being only about skills and becomes about dignity. For children 8 and older, privacy and dignity become the central concerns, and the goal shifts toward functional independence and hygiene. Bierman Autism Centers, writing for families, says that when traditional toilet training remains hard, work with medical professionals and therapists to manage incontinence respectfully8. That may include scheduled toileting routines, products designed for older children, and teaching your child to take part in their own personal care and cleanup.

Practical ways to protect dignity:

  • Choose products that look and feel like underwear. Super Undies designs its 3-in-1 to resemble regular underwear, in eight colors.
  • Change in private. Use the bathroom, and keep supplies in a discreet bag.
  • Involve your child in choices. Let them pick a color or style, and name each step of their routine.
  • Keep your tone matter-of-fact. Accidents are part of the process, and the SPARK for Autism article advises staying calm and avoiding scolding7.

If your older child needs ongoing support, protection is not a setback. It can help them stay comfortable and take part in school and community life while skills develop.

When should you involve an occupational therapist, behavior analyst, or doctor?

You don't have to do this alone. Involve a professional early if progress stalls, your child is distressed, or you suspect a medical cause. The Autism Speaks guide says that if a child is still in diapers after your own efforts, it may be time to seek help from someone with special training2, such as a physician, psychologist, special educator, speech-language pathologist, behavior analyst, or occupational therapist. It adds that intensive toilet training should be monitored by a professional.

Consider reaching out when:

  • Constipation or diarrhea is present. SPARK for Autism advises that children should not be constipated or have diarrhea when you start7, and to talk with a doctor if they are.
  • Skills regress. Look for stress, illness, medication changes, or a routine change, and ask your doctor to rule out medical causes.
  • Sensory or motor needs get in the way. Bladder and Bowel UK says occupational therapist assessment is advisable for mobility difficulties, balance problems, or severe sensory issues4.
  • Nighttime wetting continues past age 5. Assessment and treatment are available.
  • Behavior becomes a concern. Fear of the toilet, smearing, or refusing to go are worth bringing to a psychologist or occupational therapist.

Therapists can also work with products. Super Undies has a page for occupational therapists with sizing, absorbency, and product guidance, and a way to email a recommendation to a family. This article is general information and is not medical advice.

One last thought. Toilet training rarely goes in a straight line. Some weeks will feel like a breakthrough and others like a step back, and both are part of the process. Keep the routine steady, celebrate small wins, and lean on your care team when you need backup.

Frequently asked questions

Short answers to the questions parents ask most. If you only have a minute, start here.

Is it too late to potty train an autistic child at 7 or 10? No. In a study of 583 children with autism, 93.5% were dry by day by age 10. The Autism Speaks guide says its ideas may help teenagers and adults too.

How long does toilet training take? It varies widely. The Autism Speaks guide cites older research finding an average of 1.6 years of training to stay dry during the day, and sometimes more than two years for bowel control.

Should my child wear pull-ups during training? Most guides favor underwear during the day so a child can feel wetness. The Autism Speaks guide says diapers or pull-ups may be used for sleep and time away from home.

What if my child does not seem to care about being wet? Some children do not notice wetness. The Raising Children Network suggests reusable training underpants or a liner to build awareness, and pointing out wetness in a positive way.

What if my child hates wet underwear or wearing pants? Go slowly. Bladder and Bowel UK describes gradual steps, such as short periods in pants and slowly cutting away a diaper worn over them. Ask an occupational therapist for help with sensory issues.

Can nonverbal children be toilet trained? Yes. Teach a reliable way to ask, such as a sign or a picture card, and use visual schedules.

How should I handle accidents? Stay calm, change your child quickly, and avoid scolding. If accidents follow a pattern, take your child to the toilet just before those times.

When will my child stay dry at night? There is no set timeline. Night dryness develops with time and cannot be taught the way daytime dryness can. If wetting continues past age 5 after six months of daytime dryness, ask a doctor about assessment and treatment.

Which Super Undies product fits a child who is learning to use the toilet? The 3-in-1 is made for daytime and adaptive toileting, in pull-on and quick-release versions. Brain Trainers are made for children who are dry by day and still wet at night.
