Toilet training an autistic child, and starting school in nappies

Is it normal for an autistic child to toilet train later?

Yes. Later toilet training is common in autistic children and nothing to be ashamed of. In a large US study of children aged 4 and over, resistance to toilet training was reported in 49% of autistic children, compared with 24% of children with other developmental delays and 8% of other children. In autistic children it was linked with constipation and with delays in using words. In an older survey of 100 families, learning to wee in the toilet took 1.6 years on average, and learning to poo in the toilet took 2.1 years.

Toileting is a big set of skills: the charity ERIC says it involves over 40 physical and cognitive skills. But later does not mean never. National guidance from Bladder & Bowel UK says: "Assumptions should not be made regarding the ability, or lack of ability" of children and young people with additional needs to be toilet trained.

Should I wait until my child seems ready?

No. Bladder & Bowel UK's guidance (January 2025) says readiness signs are not evidence-based, and that early, structured support is appropriate. ERIC warns: "The longer your child wears a nappy, the harder it may be to introduce a new place for them to wee and poo." Instead of waiting, start by checking for constipation and keeping a simple chart of when your child wees and poos.

Why check for constipation first?

Constipation is common in autistic children and can make toilet training much harder, so treat it before you start. A meta-analysis found autistic children had nearly four times the odds of constipation compared with other children, and the US study above linked constipation with resistance to toilet training. ERIC advises making sure any constipation is treated first.

Signs of constipation listed by NICE include:

• fewer than three full poos a week
• large, hard poos, or small hard lumps like "rabbit droppings"
• very large poos that can block the toilet
• soiling: very loose, very smelly poo that leaks out without your child noticing
• straining, pain or distress when pooing, or bleeding with hard poos
• a poor appetite that improves after a big poo, or tummy pain that comes and goes with pooing
• holding on, for example standing on tiptoe with straight, stiff legs or an arched back.

The National Autistic Society also notes that some children hold on to their wee or poo until their nappy is put on.

See your GP or health visitor if you notice these signs. NICE says changes to diet should not be used on their own as the first treatment. It also says treatment should continue for several weeks after your child is pooing regularly, which may take several months, and should then be reduced gradually rather than stopped suddenly. Ask your GP before stopping any treatment.

How do I toilet train my autistic child step by step?

Teach one small step at a time, the same way every time, with pictures your child can follow.

1. Treat constipation first, with help from your GP or health visitor.
2. Chart for a few days. The National Autistic Society suggests watching "over a few days to see when they do a wee or a poo", so you can take your child when they are most likely to go. Note the time and whether your child was wet, dry or had a poo.
3. Make a picture sequence of your own bathroom. ERIC suggests photos or drawings of each step: trousers down, pants down, sit, wee or poo, wipe, pants up, trousers up, flush, wash hands. Put it beside the toilet and keep the sequence the same every time. Our toileting sequence printable is ready to use.
4. Set up the bathroom. Use a footstool so your child's feet are supported, a child seat if needed, and fix any sensory problems (see the table below).
5. Choose easy clothes, such as joggers with an elastic waist, that your child can pull down and up.
6. Sit at regular times based on your chart, such as after meals. Keep sits short and relaxed, with a book or toy that stays in the bathroom.
7. Praise effort, not just results. ERIC advises praising "the efforts they are making, not just the result". The National Autistic Society notes that some children like a "well done" or a tickle, while others respond better to an object. If you use a reward, let your child choose it beforehand and give it straight away.
8. Stay calm about accidents. The National Autistic Society suggests getting your child to the toilet quickly so some wee goes in, then ignoring the wetting and praising the wee that went in the toilet. Never punish or tell your child off for accidents.
9. Agree one approach with nursery or school. The National Autistic Society advises that everyone starts at the same time and follows the same plan, and that you send in any equipment you use at home.

If your child is non-speaking or uses few words, give them a simple way to say "toilet", such as a toilet picture to hand over or point to, or a sign. Our guide to signing, pictures and AAC explains the options.

What if the toilet itself upsets my child?

Sensory differences can make a bathroom hard to be in. The National Autistic Society asks: "Does the soap smell too strong for them? Does the noise of the extractor fan bother them?" ERIC suggests adjusting lighting, noise and textures to suit your child.

Public toilets can be harder, with loud hand dryers and automatic flushes. Take ear defenders, and practise in quieter toilets first. Our guide to sensory differences has more ideas.

Can my child start nursery or school in nappies?

Yes. The National Autistic Society says: "Admission to school should not be refused simply because a child has difficulties with continence." ERIC says schools cannot refuse admission on continence grounds under the Equality Act 2010, and that the Children and Families Act 2014 gives schools a duty to support pupils with medical conditions, including bladder and bowel problems.

In England, statutory guidance for schools (December 2015) says it is not acceptable to "require parents, or otherwise make them feel obliged, to attend school to administer medication or provide medical support to their child, including with toileting issues". It adds: "No parent should have to give up working because the school is failing to support their child's medical needs."

Before your child starts, ask for:

• an individual healthcare plan that covers toileting (ERIC)
• who will change your child, and where; ERIC says only one member of staff needs to be present, as long as another is nearby
• regular toilet trips built into the day, with the same pictures and words as at home
• a discreet toilet pass for older children (ERIC)
• spare clothes and products kept at school, and how staff will tell you about progress.

For nurseries and childminders, talk to the manager before your child starts about how they will support toileting, and agree the same approach as at home. If a nursery or school says your child cannot start until they are toilet trained, get advice from your local SENDIASS or IPSEA. Our guide to starting nursery or school has more.

Can I get free nappies or pads from the NHS?

Not before age 5, and after that only following an assessment. Under national guidance from Bladder & Bowel UK (January 2025):

• NHS continence products, such as nappies or pads, are not provided before a child's fifth birthday.
• From age 5, they depend on a full bladder and bowel assessment and at least 6 months of a supported toilet training programme that has not led to enough progress.
• The assessment includes at least a 3-day bladder chart, 2 weeks of bowel monitoring and a check of toilet skills.
• Supplies would typically be no more than 4 products a day.

Local NHS services decide how this works in their area, so details can differ. For example, one NHS service supplies products for 16 weeks at a time after assessment, needs a face-to-face review once a year, and does not supply them for treatable conditions such as bedwetting, soiling or constipation. Ask your health visitor, school nurse or GP about your local continence service.
