Introduction
Bedwetting — or nocturnal enuresis — is one of the most common childhood concerns, and many families in Dunedin and across Otago find themselves unsure where to turn for help. The good news is that bedwetting is usually a normal part of development, and with the right guidance, most children achieve nighttime dryness confidently.
As a paediatric pelvic health physiotherapist based here in Dunedin, I see firsthand how much relief families feel when they finally understand why bedwetting happens and what they can do about it. This blog is designed to give you clear, practical guidance you can trust.
What Is Bedwetting?
Bedwetting is when a child empties their bladder during sleep after the age when nighttime dryness is typically expected. Most children achieve nighttime dryness between ages 5–7, but around 15–20% of five‑year‑olds still wet the bed. It’s common, it’s normal — and it’s treatable. Families in Dunedin often seek support when bedwetting becomes stressful, impacts sleep, or starts affecting a child’s confidence.
Why Does Bedwetting Happen?
Bedwetting is rarely caused by laziness or behavioural issues. Instead, it’s usually linked to one or more of these factors:
1. Deep Sleep Patterns
Some children sleep so deeply that their brain doesn’t register the bladder’s “full” signal.
2. Bladder Maturity
The bladder and brain simply need more time to coordinate overnight dryness.
3. Genetics
If one parent wet the bed, the child has a 40% chance of experiencing it too. If both parents did, the likelihood rises to 70%.
4. Constipation
A full bowel presses on the bladder, reducing its capacity and increasing nighttime accidents. Constipation is one of the most overlooked contributors.
5. Overnight Urine Production
Some children produce more urine at night due to lower levels of the hormone vasopressin, which helps concentrate urine.
6. Daytime Bladder Habits
Rushing, “just in case” wees, or holding for long periods can all affect nighttime control.
When Should Dunedin Families Seek Help?
Most bedwetting is simply developmental. However, it’s worth seeking support if:
- Your child is over 7 and still wetting regularly
- Bedwetting is causing distress or embarrassment
- Your child has daytime accidents
- Your child has ongoing constipation
- Bedwetting started suddenly after a long period of dryness
Early support can make a huge difference — especially when families feel stuck or unsure what to try next.
What You Can Do at Home
These simple strategies often help improve nighttime dryness:
1. Prioritise Daytime Toileting
- Encourage regular wees every 2–3 hours
- Support relaxed, unhurried toileting
- Ensure proper posture: feet supported, knees above hips
2. Address Constipation
Healthy bowel habits are essential. Look for: infrequent stools, large stools, skid marks, tummy pain, or withholding behaviours.
3. Hydration Matters
Aim for most fluids earlier in the day. Avoid restricting fluids — instead, spread them evenly and reduce close to bedtime.
4. Bedtime Routine
- Encourage a calm wind‑down
- Ensure a final relaxed wee before sleep
- Avoid bladder irritants in the evening (e.g., fizzy drinks, chocolate, citrus)
5. Stay Positive
Children don’t wet the bed on purpose. Your calm reassurance helps protect their confidence.
What Treatments Are Available?
If home strategies aren’t enough, evidence‑based options include:
Pelvic Health Physiotherapy
A paediatric pelvic health clinician can assess:
- bladder habits
- bowel function
- pelvic floor coordination
- sleep patterns
- fluid intake
- family history
- reflex integration
- acupressure points for bed wetting and constipation
- mobilisations techniques for pelvic mobility
From there, we create a personalised plan that supports both the child and the family.
Bedwetting Alarms
Can be effective treatment for some children. Alarms help the brain learn to respond to bladder signals overnight. They are best used once all other factors have been addressed e.g constipation and daytime bladder strategies.
Bladder Training
Improving daytime habits can significantly improve nighttime dryness.
Medical Support
In some cases, medication may be appropriate — usually when alarms aren’t suitable or haven’t worked.
How Core Foundations Can Help
Core Foundations is Dunedin’s dedicated paediatric pelvic health service, supporting children and families with bladder, bowel, and pelvic floor concerns.
I take a gentle, child‑centred approach, helping families understand what’s happening, reduce stress, and build healthy habits that support long‑term success.
If your child is experiencing bedwetting and you’re based in Dunedin, Mosgiel, the Taieri, or wider Otago, you’re welcome to reach out for an assessment or personalised plan.
Bedwetting is treatable — and your child is not alone.
