Bedwetting Information

Bedwetting is a common problem with more than 4.8 million Australians experience bed wetting or other forms of incontinence. In children, bedwetting affects up to 1 in 5 children and the age at which children become able to control their bladders at night varies.

Sleep Solutions provides a range of  products to help both children and adults manage the condition from sheet and mattress protectors, to bedwetting alarm systems.

How does a Bedwetting Alarm work?

A bedwetting alarm is a device that is designed to help stop night time bedwetting (also known as nocturnal enuresis) by alerting the user when they begin to wet the bed. The alarm typically consists of a sensor that is placed in the child's underwear or pajamas and is connected to an alarm that is worn on the child's wrist or placed next to their bed.

When the sensor detects moisture, it triggers the alarm to sound. The alarm is loud enough to wake the child, and the child should get up to use the toilet. Over time, the child's brain learns to associate the sensation of a full bladder with the sound of the alarm, and they will eventually wake up before they wet the bed.

Bedwetting alarms can also be combined with other treatments such as motivational therapy which can be provided by a pediatrician or a behavioral therapist. It is important to note that bedwetting alarms are not an overnight solution, it may take time, patience and consistency in using the alarm for it to be effective.

The Complete Guide to Bedwetting Alarms

Understanding nocturnal enuresis, choosing the right alarm, and a proven action plan to help your child achieve dry nights.

Understanding Bedwetting: A Normal Developmental Stage

Bedwetting-clinically known as nocturnal enuresis-is a very normal and natural developmental stage. It is rarely caused by medical or behavioural issues, and it is important to remember that children do not do it on purpose.

If you are exploring options to help your child achieve dry nights, it helps to know just how common this is in Australia. According to national health statistics and the Continence Foundation of Australia:1, 2

1 in 5 Five-year-olds in Australia wet the bed. It still affects about 10% of 10-year-olds.
2x Boys under 9 are roughly twice as likely to experience bedwetting compared to girls.
75% If both parents wet the bed as children, their child has a 75% chance of doing the same.3

For a broader understanding of underlying causes, paediatric milestones, and general management strategies, please refer to our comprehensive Australian Children's Bedwetting Guide.

How Do Bedwetting Alarms Work?

Bedwetting alarms do not magically stop the flow of urine. Instead, they use a highly sensitive moisture sensor to trigger a sound or vibration at the very first drop of moisture. This works through a psychological process called conditioned learning.

Extensive clinical reviews by the Cochrane Library have concluded that alarm therapy is the most effective long-term treatment for bedwetting. Compared to other methods, it results in a significantly higher percentage of children achieving complete, permanent dryness.4

Choosing the Right Style

Comfort and practicality are the most important factors when selecting an alarm, as a child must be willing to use it every single night. Select an alarm type below to learn more.

Wearable (Wired)Wearable (Wired) Alarms

The traditional standard. A small moisture sensor clips to the outside of the child's underwear, and a thin wire runs under their pyjama shirt to a compact alarm unit clipped near their shoulder.

✓ Pros

Highly responsive to the first drop of moisture. Because the alarm sounds right next to the ear, it is highly effective for waking the child.

✗ Cons

Some sensory-sensitive children dislike the feeling of the cord, and restless sleepers may occasionally tangle the wire during the night.

Our Recommendation

WirelessWireless Alarms

Wireless alarms eliminate the cord entirely. A small, lightweight sensor clips to the underwear and transmits a signal wirelessly to a receiver unit placed elsewhere in the room.

The Dual-Receiver Advantage: We highly recommend the Malem Wireless Bedwetting Alarm (Model MO12). This system supports dual receivers-one in the child's bedroom and a second directly in the parents' bedroom. This guarantees parents hear the alarm instantly, allowing them to assist and coach the child immediately.

✓ Pros

Extremely comfortable with no cords to tangle. Placing the receiver across the room forces the child to physically get out of bed to turn it off, ensuring they wake up fully.

✗ Cons

Typically a higher initial investment, and sensors require routine charging or battery replacement.

Alarm MatBedwetting Alarm Mats (Bell and Pad)

Ideal for children who refuse to wear clips or sensors on their pyjamas. Instead of a wearable device, a flat, moisture-sensitive pad is placed underneath the child on top of the mattress, connecting to an alarm unit on the bedside table.

✓ Pros

Zero bodily contact, making it perfect for children with strong sensory aversions.

✗ Cons

The child must be positioned on the mat for it to trigger. There can also be a slight delay if urine has to soak through thick winter pyjamas before reaching the sensor.

The Action Plan: What to Do When the Alarm Sounds

Using an alarm is a team effort. Parents must be highly involved as coaches, especially in the first few weeks. Click each step below for additional detail.

1
Go to the child immediately

Do not wait for them to turn the alarm off on their own.

The first weeks are critical for building the conditioned response. Your speed matters-getting there quickly reinforces the connection between the alarm sound and the waking moment.
2
Wake them fully

Ensure their eyes are open and they are conscious. Turn on a soft nightlight.

This is essential for the brain-training process. A semi-conscious child won't form the neurological connections needed. Sit them upright, speak clearly, and wait until they can respond to you before proceeding.
3
Turn off the alarm

Have the child press the reset button themselves to build muscle memory and independence.

Even if it's easier for you to do it, letting the child physically interact with the alarm each time builds ownership and independence, which speeds up the overall training process.
4
Go to the toilet

Walk them to the bathroom to finish urinating, even if they say their bladder is empty.

Important: Never carry a sleeping child to the toilet, as this bypasses the brain-training process. The child must walk themselves to reinforce the waking-bladder connection.
5
Change and Reset

Help them into dry clothes, wipe down the sensor, and reset the alarm for the rest of the night.

Keep a small basket of clean pyjamas and underwear beside the bed so you don't need to rummage through drawers at 2 AM. A quick wipe of the sensor with a damp cloth is all that's needed before re-attaching it.
Pro Tip - The Double-Make Method

To make 2:00 AM bed changes stress-free, "double-make" the bed before sleep. Layer a waterproof mattress protector, then a fitted sheet, then another waterproof protector, and another fitted sheet. When the bed is wet, simply strip off the top two layers. You instantly have a clean, dry bed ready underneath!

Timelines, Expectations & What to Expect

Patience is essential. Clinical guidelines suggest it takes an average of 10 to 16 weeks (roughly 2 to 4 months) to achieve complete dryness. Treatment should be continued every single night until your child has achieved 14 consecutive dry nights.

10 – 16 weeks to full dryness
Weeks 2 – 3 Early Signs Smaller wet patches on the bed. The child may begin stirring when the alarm sounds.
Weeks 4 – 8 Progress Builds The child starts "beating the buzzer"-waking up to use the toilet before the alarm triggers.
Weeks 10 – 16 Dry Nights Consistently dry nights. Continue until 14 consecutive dry nights are achieved.

Addressing Heavy Sleepers

The most common issue parents face is that their child sleeps right through the loud alarm. This is completely normal. Remember that the parent acts as the primary backup alarm. You must hear the device and physically wake the child up so their brain can make the necessary connections.

For specific strategies on managing this, please read our guide on Tips for Using Bedwetting Alarms with Kids that are Heavy Sleepers.

Frequently Asked Questions

What causes bedwetting?

Bedwetting, medically known as nocturnal enuresis, is a common occurrence, especially among children. It refers to involuntary urination during sleep, and while most children outgrow it, some can experience it into adolescence and even adulthood. Several factors, both physical and psychological, can contribute to bedwetting.

Primary causes and factors linked to bedwetting include:

  • Bladder Size: A small bladder or one that doesn't empty fully can lead to bedwetting. Some children's bladders can't hold a large volume of urine.
  • Deep Sleep: Some kids sleep so deeply that they don’t wake up when they need to urinate.
  • Delayed Bladder Maturation: In some cases, the child's bladder might be slower to develop control mechanisms that prevent nighttime wetting.
  • Hormonal Imbalance: A hormone called vasopressin reduces urine production at night. Some children might not produce enough of this hormone, leading to increased nighttime urine.
  • Urinary Tract Infections: Infections in the urinary tract can make it difficult for children to control urination. Symptoms may include day and night wetting, frequent urination, or pain during urination.
  • Constipation: Full bowels can press against the bladder, reducing its holding capacity. Regular bowel movements are crucial for preventing bedwetting.
  • Stress and Anxiety: Emotional factors like moving to a new school, the arrival of a sibling, or any situation causing anxiety can trigger bedwetting.


Understanding the potential causes is vital for addressing and managing bedwetting. If it persists or begins suddenly, especially in older children or adults, consulting a healthcare professional can provide insights into underlying issues and suitable treatments.

Is bedwetting normal in kids?

Bedwetting, also known as nocturnal enuresis, is a common occurrence among children. While it can be a concern for many parents, it's essential to understand that most children will outgrow bedwetting, and it's typically not a sign of any serious medical issues. It's a natural part of a child's developmental process and, in many cases, is related to the maturation of the bladder and the central nervous system.

Considerations regarding bedwetting in children include:

  • Age Factor: Many children under the age of 5 haven't yet developed full nighttime bladder control. As a result, occasional bedwetting in this age group is completely normal.
  • Developmental Variation: Children develop bladder control at different rates. Some may remain dry at night earlier than others, and occasional wet nights can persist even in kids older than 5.
  • Genetics: Bedwetting can run in families. If one or both parents experienced bedwetting as children, their offspring might be more likely to wet the bed.
  • Deep Sleepers: Some children sleep so deeply that they don't wake up when their bladders are full. This can lead to occasional bedwetting episodes.
  • Stress: Changes in a child's routine, such as starting school, facing family issues, or experiencing significant life events, can sometimes trigger bedwetting.

In conclusion, while bedwetting is a standard part of childhood for many, if there are concerns or if the condition persists or occurs suddenly in older children, it's beneficial to consult a healthcare professional. They can provide guidance, reassurance, and if necessary, interventions to assist the child and family.

How do kids bedwetting alarms work?

Kids' bedwetting alarms are a practical tool designed to assist children in overcoming nocturnal enuresis (bedwetting). These alarms are equipped with a moisture sensor that detects urine. When wetness is sensed, the alarm sounds, vibrates, or does both, alerting the child to wake up and go to the toilet. The primary aim is to train the child's brain to recognise the sensation of a full bladder during sleep and wake up before wetting the bed.

Here's a more in-depth look at the working mechanism and features of bedwetting alarms:

  • Moisture Sensors: These sensors are placed either on the child's underwear or on the bedsheet. They are highly sensitive and can detect the slightest moisture, triggering the alarm immediately when wetting starts.
  • Alarm Unit: Upon detecting moisture, the alarm unit (usually clipped to the child's pajama top or placed nearby) emits a sound, vibrates, or both. This alerts the child and prompts them to wake up and use the toilet.
  • Types of Alarms: There are various models available. Some come with wireless sensors, while others have wired connections.
  • Training Process: Over time, the child learns to associate the sensation of a full bladder with the need to wake up, eventually preempting the alarm. This behavioural conditioning aids in the development of consistent night-time bladder control.
  • Safety: Bedwetting alarms are safe to use. It's essential to choose models that are certified and to follow manufacturer instructions for optimal and secure use.


Consistency is key when using bedwetting alarms. While some children might show improvement within weeks, others may take a few months. Parents and caregivers should offer encouragement and patience during this process, celebrating small achievements to boost the child's confidence.

Which types of kids bedwetting alarms are best?

Choosing the right bedwetting alarm for a child can make a significant difference in their journey to overcome nocturnal enuresis. Various types of alarms cater to different needs and preferences. To select the best option, it's essential to consider the child's comfort, the ease of use, and the effectiveness of the alarm.

Here are the primary types of kids' bedwetting alarms and their features:

  • Wearable Alarms: These alarms come with a moisture sensor that attaches to the child's underwear. The alarm unit is typically clipped to the pyjama top. When moisture is detected, the alarm sounds, waking the child up.
    • Pros: Portable, direct contact with moisture.
    • Cons: Wires might be uncomfortable for some kids.
  • Wireless Alarms: A sensor is placed in the child's underwear, but the alarm itself is separate, often kept on a bedside table. The two components communicate wirelessly.
    • Pros: No wires to entangle, comfortable.
    • Cons: Might be less sensitive than direct-contact models.
  • Pad-type Alarms: A moisture-sensitive pad is placed under the child, and the alarm sounds when the pad detects wetness.
    • Pros: No need to attach anything to the child's clothing, suitable for heavy sleepers.
    • Cons: Less portable, might miss very small leaks.


When choosing an alarm, consider your child's preferences and sleeping habits. It's essential that the child feels comfortable using the device. Read our customer reviews and recommendations to ensure you opt for a reliable and effective bedwetting solution.

How to prevent bedwetting with kids?

Bedwetting, medically termed nocturnal enuresis, is a common occurrence in children. While many kids outgrow this phase naturally, preventive measures can be taken to help reduce the frequency of bedwetting and support the child in achieving dry nights.

Here are practical strategies to help prevent bedwetting in children:

  • Establish a Routine:
    • Consistent Bedtime: A regular bedtime helps the child’s body clock get accustomed to a routine.
    • Toilet Breaks: Encourage the child to use the toilet right before going to bed to empty their bladder.
  • Limited Evening Fluids: While it's essential to stay hydrated, try to limit excessive fluid intake in the evening. Ensure the child drinks adequately during the day instead.
  • Dietary Watch: Avoid foods and drinks with caffeine, like chocolates or soft drinks, especially in the evening as they can stimulate the bladder.
  • Bladder Training: This involves setting regular intervals for toilet breaks during the day, gradually extending the time between them to help the bladder hold more urine.
  • Use Protective Bedding: Waterproof mattress protectors can help in case of accidents, making nighttime clean-ups easier and less stressful.
  • Positive Encouragement: Praise and rewards for dry nights can boost a child’s confidence and motivation. Avoid showing disappointment or frustration during wet nights.
  • Seek Medical Advice: If bedwetting persists or there are other accompanying symptoms, consult with a paediatrician to rule out underlying medical conditions or infections.


While these strategies can be beneficial, it's vital to remember that bedwetting is typically a phase in a child's development and is rarely due to laziness or defiance. Offering support, understanding, and reassurance can make a significant difference in a child's bedwetting journey.

Is bedwetting more common in boys or girls?

Bedwetting, clinically known as nocturnal enuresis, is a typical part of childhood for many kids. It's a concern that many parents face, often leading to questions about its prevalence among different genders. Studies and clinical observations have consistently shown differences in the rates of bedwetting between boys and girls.

Based on available data:

  • Prevalence: Bedwetting is generally more common in boys than in girls. While the exact reasons for this disparity aren't entirely understood, this trend is observed across multiple cultures and populations.
  • Outgrowing Phase: Both boys and girls typically outgrow bedwetting as they age. However, some studies suggest that girls tend to achieve nighttime dryness at an earlier age compared to boys.
  • Underlying Factors: The reasons for the gender difference in bedwetting rates could be multifaceted, involving anatomical, physiological, and developmental factors. For instance, the maturation process, bladder capacity, and hormonal influences might differ between boys and girls, potentially impacting the rates of nocturnal enuresis.


It's essential for parents to understand that bedwetting is a natural part of childhood development for many kids, regardless of gender. It is important to provide support, understanding, and appropriate interventions if necessary to help children manage and eventually overcome this phase.
