Bedwetting can best be defined as the uncontrollable urinating while sleeping. When bedwetters are awake, no problems occurs. This in contrast with incontinence patients which wet themselves during both day and night. Although it is not well-known, bedwetting occurs as well frequently during adulthood. Studies have proven that about 1% of adults keep bedwetting. The problem occurs more with men than women. Some of them wet their bed every night and others just now and then.

Bedwetting is not a disease, it is an awkward problem.

For those persons who are troubled with bedwetting, it is very troublesome and far-reaching. The social consequences can be staggering. They feel ashamed and are not open about it. Out of fear of wetting the bed at other places, they do not stay over for the night at friends and family places. Do not dare going on a school camp or having problems entering a relationship.

It is normal for a baby and children up to about three years, for five-year-old children it is unpleasant and for older children it can become a complete obsession for themselves and for the whole family. At mature age it often disappears by itself, however there are adults who still wet their bed.

More than 15% of all six-year-olds and 5% of the ten-year-olds are not dry at night. For the category between fifteen and eighteen year-olds it is 1.5% by estimation. It is not exactly known how many adults are struggling with this problem, because this issue is a taboo. Bedwetting occurs with boys twice as much as with girls, a clear explanation is not known.

At first it is important that the one who wets the bed urinates regularly by day. When you drink 6 to 7 glasses per day, it is normal that you urinate about 5 to 6 times by day. It is quite simple to monitor it during 3 days. If the pattern is deviant by day, it is the best to consult with your family doctor.

When there are no (more) problems by day one can try to start with a specific treatment to end bedwetting. You would be well-advised to contact your family or school doctor.

Before you start with the treatment, your doctor will check for other causes. By young children one starts usually with a treatment only when the child experienced it as a problem and wants to assist the treatment. Only then you have a chance to complete the treatment successfully.

Frequently after a few days progress will occur and after a matter of weeks the problem is solved. Motivation and perseverance are the key combination, both for the parents and the child. A successful treatment with the Rodger bedwetting system takes rarely more than 3 months.

Daytime wetting

Problems with toilet training for urine and / or feces are common and can have a significant impact. For 4-7 year olds is daytime wetting in about 7% of the children an issue and it is an important psychosocial problem. The problem may persist into adulthood. Besides the psychological effect on the welfare of children and their parents, there are also social disadvantages: an untrained child creates extra work and extra costs.

Various studies show, that children when toilet trained by guidance and various treatments, are dry faster than waiting till the child becomes spontaneously dry.Most children at the age of 30-36 months are dry during the day and at the age of 36-48 months dry at night. A child is able to be first dry during nights and after that during the day.

The length of a normal potty training varies from child to child, but you have to invest at least three months of training to learn your child to become dry. The standard toilet training starts first practicing with a potty and then stop using a diaper during the day. Afterwards stop using a diaper overnight. Before starting, it is important that the child feels open to start potty training.

Many children ignore their bladder signals when they are too engrossed in their game. This can lead to the so called ‘game-enuresis’; the pant wetting during game play.

Sometimes there is a physical cause for pants wetting such as an urinary tract infection. In case of doubt or complaints it is wise to contact your General Practice. Normally, a wet suit is for the child at least as annoying as for yourself. Sometimes at school, children may say your child carries an urine smell, this must be an annoying experience for your child and you too. It is important not to get angry on your child. Your child, in fact, cannot do anything about it.

If the child becomes not dry automatically, then additional support is required. Please do not start on own initiative with a day alarm system. It may be a fact, that there is a physical cause for not being dry during the day and then eventual alarm symptoms should be excluded.

Commonly there is a progress observable within a few days. The problem of daytime wetting is solved within a few weeks. Perseverance is, among motivation from parent and child necessary and are the key to success.


Yes, but it is only useful if your child is completely awake. Otherwise your child shall not learn the difference between pee in the bed or at the toilet. When your child wet’s the bed as well after that extra toilet use at night, then it is not (yet) useful to do.

No, it is not. Although it is wise to give your child good to drink in the mornings. A child that is thirsty in the afternoon or evening did drink too little during the day.

Most children are potty trained during days when they are 3 or 4 years of age. From the age of 7, most children are dry at nights too.

Almost every child wakes up him or herself hearing the alarm. The volume of the alarm is not always deciding for the waking up moment from the child. The designing and research company Rodger BV paid a lot of attention to the available and different types of sounds. However, a small number of children do need additional attention. Often is to sleep beside your child in the same bedroom an accurate solution. You are just a second away to help your child wake up after the very first sound of the alarm system. The first seconds are crucial for waking up and hearing the sound. Should you have to come from another room or floor, it could take minutes. Your child is already in a deeper sleep again.


Bed-wetters often feel ashamed about it and have low self-respect due to their bedwetting. Children often feel lonely because of their bedwetting.

Both usually work very counterproductive and unfortunately contribute to further underdevelopment of the urinary system. Although it is advisable not to drink coffee, tea, chocolate milk or carbonated drinks after supper/dinner. Actually, we do not advise you to wake your child at night to go to the toilet. Your child needs to learn to wake up himself having a full bladder. That will usually not be the case when you let him wake up to go to the toilet.

There are children who will be dry within 1 or 2 nights. There are also children who need 3 to 4 months to train.

If there is no progress after 3 months, we advise you to get in contact with your supervisor again. Is there some progress after 3 months though, continue with the 4th month. If the child is still not dry afterwards, please contact your supervisor. If your child is younger than 6 years of age and there is no significant progress after 3 months, you better put the bedwetting alarm system aside for half a year and start again afterwards. Your child is certainly not ready for training yet.

If you do not undertake any action against bedwetting, it might be a struggle and problem till adulthood. Each year of bedwetting causes further physical underdevelopment of the bladder and unnecessary embarrassment and emotional pain for the bed-wetter.

Approximately 10% till 15% of bed-wetters will get dry themselves annually. This means that from 100 bed-wetters, 85 till 90 persons are still bed-wetters after 1 year! Why should you not help your child to get rid of the bedwetting problem?

Medicines are artificial ways to eliminate the sleep and/or to reduce production of urine. When treatment has stopped, a relapse is possible since the cause has not been resolved. It is known that the percentage of children which had a relapse after using a bedwetting alarm system, is significantly lower. It certainly can happen that a doctor prescribes medication for specific reasons. This also happens in combination with a bedwetting alarm system.
