Origins of the bedwetting alarm

The bedwetting alarm method was discovered by accident around 1920. A German pediatrician, Meinhard von Pfaundler, he was looking for a way to let the nursing staff know when a child had wet the bed. He found it annoying if the children lay in a wet bed for a long time and wanted to help both the children and the nursing staff with that. He developed a device that would sound an alarm if a child had a wet bed. Coincidentally, they also found that the children who used this method were more likely to be potty trained. It later turned out that this bedwetting alarm training was a resounding success.



It was not until the 1930s that the effectiveness of the bedwetting method was investigated by two psychologists. Here, through an empirical test with thirty children between the ages of 3 and 13, it was shown that bedwetting training was an effective remedy. It was also found that the average duration of a bedwetting training program is a maximum of three months. This is still true today and if after three months children are not potty trained at night with the use of the bedwetting method and the bedwetting training it is a good idea to see your doctor.

How does the bedwetting alarm method and bedwetting alarm training work?

The bedwetting alarm method is based on both classical and operant conditioning. The alarm that sounds during urination causes children to at some point make the connection between a full bladder and needing to go the bathroom themselves. Initially, the alarm will cause the child to startle, wake up and tighten the sphincter of the bladder. The behavior is then learned during this period.

When the bedwetting alarm training is followed for a few weeks, the child will make a connection between the alarm and a full bladder. Because the behavior is taught to go to the bathroom, when the bladder is full, the child will wake up and go to the bathroom by himself. This process is called classical conditioning.

Operant conditioning is a process in which human behavior changes as a result of consequences of that behavior. In the case of the bedwetting method, the consequence of bedwetting is that the alarm goes off. This is something a child would rather avoid, because it is not nice to be woken up in the middle of the night.... Through the bedwetting alarm training, the child better recognizes the full bladder, but also starts to do his/her best to avoid being woken up by the alarm.

It is important to reward a child on dry nights. This will increase the effectiveness of the bedwetting alarm training.

The Dryly® urinary alarm method.

The bedwetting method is an effective way to tackle bedwetting but how does the bedwetting method work? Your child puts on special Dryly® underwear before bed that, via a transmitter, is connected to our mobile app and to the receiver hidden in Wizzu (panda toy). For older children, the receiver can be used separately. Both the panda, and the mobile app work as an alarm. Wizzu for your child and the mobile app for you, as a parent. This gives you insight into when and how often your child pees each night.

This way you know exactly when your child wets the bed and you can help your child continue peeing on the toilet! As soon as the pants get wet, both alarms go off. Thus, this bedwetting alarm training trains your child to wake up to a full bladder. The bedwetting alarm method is proven successful because the bedwetting alarm training subconsciously creates recognition of the problem and the will to solve it.



Support as a parent to your child with bedwetting problems is crucial to the success of bedwetting training with the bedwetting method. This is why we provide insight into your child's behavior through the mobile app. Wizzu is proudly central to this pee wake method and should really become the friend, supporting your child in the process of becoming dry.

Before you start the bedwetting alarm training of the Dryly® bedwetting alarm method, set up the mobile app with your child. This is fun and motivating for your child because Wizzu plays the lead role in the app. You enter your child's name, age and gender so that the app can best help you in the process of becoming dry.

Next, explain to your child the purpose of the bedwetting alarm training. On the first night, have him/her practice putting on and taking off the pants and turning on and off the Dryly® Receiver (in Wizzu (panda toy). Together with urologists, we have developed a special bedwetting alarm training ritual before your child goes to bed.

  • The Dryly® ritual is very important, the app helps you with this. Follow the instructions on the app and get a good start for the night!
  • If the panda goes off at night, go to your child's bedroom and turn on the light. Wait until your child turns off the sound himself and goes to the bathroom. Give compliments when this goes well, both at the time and the next morning.
  • If it takes more than three minutes for your child to turn off the panda, gently wake him/her up. Let your child go to the bathroom without praising him/her. Pay no attention to being wet. Your child is still supposed to wake up to the sound of Wizzu (and not the parents).
  • If your child wakes up because of the panda, it counts as a successful night. For this, your child receives points in the mobile app. With these points, he/she can buy fun gadgets for Wizzu.
  • Bedwetting training through our Dryly® bedwetting method will not solve the bedwetting problem all at once, but the goal is to create a positive trend where the child wets the bed less and less often.

Bedwetting and deep sleep

Bedwetting children are often deep sleepers and therefore have difficulty waking up. If this is also the case with your child, he or she may not wake up to the sound the first few times. In this case, wake your child quietly so that habituation occurs. After one to four weeks, you will notice that the sleep becomes less deep and your child wakes up more easily!

When do you use the bedwetting alarm?

If you are reading this, you probably already meet the first criteria! If a child is still not potty trained from the age of 5, and wets the bed several times a week, it is a good idea to explore the options. Of course, parents are free to start earlier, but most health insurance companies do not reimburse the bedwetting alarm until the age of 5-6.

Of course, it is important to visit the family doctor first to rule out that physical problems are the cause. However, research shows that bedwetting has no physical cause in 98% of children.

Who is the bedwetting alarm suitable for?

The bedwetting alarm is suitable for children aged 3-14 years, as well as adults. The recommended age is from 5 years onwards, It is especially important that both the parent and the child are motivated to tackle the bedwetting problem! As a parent, you will need to support your child during the night and the child's motivation is also crucial.

How quickly does the bedwetting alarm give results?

Every child that wets the bed is different and this is reflected in the treatment times. One child gets used to it right away and quickly stops bedwetting, in the other child the problem is a bit deeper so more time is needed.

According to one study, it takes an average of 52 days for a child to go 4 consecutive weeks without wetting the bed. One child is dry after 3 weeks and the other after 4 months.

How successful is the peeing alarm method according to science?

A study at the University of Alberta on the effectiveness of the bedwetting alarm showed that 66% of the children studied were dry for at least 14 consecutive nights after 10 to 20 weeks. The control group showed an improvement of 4%.

Another study conducted in cooperation with the TNO in Leiden shows that 85.5% of the children were dry for 4 weeks immediately after the bedwetting alarm treatment. After 2 years, these were 76.7%.

An interesting observation shows that of the dry children, 15.2% woke up every night to pee versus 3.9% of the children who were wet. 51.5% of the dry children sometimes woke up to pee versus 27.5% of the children who were wet.

Among users of the Dryly bedwetting alarm method, 93% are currently potty trained within 6 to 8 weeks.

Among users of the Dryly potty training method, 93% are currently potty trained within 6 to 8 weeks.

  • Never knew a dryly bedwetting alarm would be a godsend! An alarm clock in the shape of a soft toy and no one sees that you have a bedwetting alarm in your room. We ordered a package with 4 underpants was cheaper than loose and then unfortunately No reimbursement from the insurance I thought at first, quite an expense but actually you can strip the money away.

  • Fine program! Top system for our son. Only the pants are quite small and too bad that wizzu only has 1 alarm sound. Otherwise a super program.
  • Shipping took a little long, but her product is top notch! Daughter loves it with the toy and the app and is super motivated partly because of it!
  • What a great invention!!! I was suspicious about the bedwetting alarm at first but immediately after 1 week of use we saw progress. Meanwhile both sons are potty trained with Dryly's bedwetting alarm. Huge pluses for the fun method and playful approach!!! Dryly thanks for your invention.

  • Our 7-year-old son wet his bed so much every night that no diaper could stop it. When we saw dryly passing by on Facebook, we were a little skeptical at first. Because we became so despondent about the situation, we decided to purchase a dryly bedwetting alarm anyway.
  • After also sending an email to dryly they called me nicely And walked me through the program the device is now working properly. The telephone support is really perfect this man took all the time.
  • Setting up the dryly was a little tricky at first because it kept not picking up our WiFi network. But after a call to the fine customer service department, the system worked fine after a reset. The app works with a reward system which made us enthusiastic to get started. The first nights we got 2-3 reports of accidents every night.

  • Daughter of 5 was wet every night, therefore chose to order the dryly. The first week she did not wake up despite the vibrate function. The 2nd week this was different and she did wake up from the alarm and vibration function, but in a wet bed. The 3rd week she woke up immediately from the alarm as soon as there was 1 drop in the pants, this made her stop and go to the toilet.
