Bedwetting in Childhood


PDF   |  音频

What is bed-wetting?

Bed-wetting (also called nocturnal enuresis) is when the bladder empties while a child is asleep. This can happen every so often, or every night.

Bed-wetting is common. About one in every five children in Australia wets the bed. Bed-wetting can run in families and is more common in boys than girls before the age of nine years. It can be upsetting for the child and stressful for the whole family. The good news is that you can get help.




What causes bed-wetting?

Wetting the bed is caused by a mix of three things:

  • the body making a large amount of urine through the night;
  • a bladder that can only store a small amount of urine at night; and
  • not being able to fully wake up from sleep.

Children who wet the bed are not lazy or being naughty. Some illnesses are linked with bed-wetting, but most children who wet the bed do not have major health problems.

Day-time control of the bladder comes before night-time dryness. Most children are dry through the day by the age of three years and at night by school age. However, this can vary, and children may have accidents every so often, both day and night, up until they are seven or eight years of age.



  • 身體在夜間產生大量尿液;
  • 膀胱在夜間只能儲存少量尿液;以及
  • 兒童無法從睡眠中完全醒過來。



When should you seek help for bed-wetting?

It is best to seek help from a health professional with special training in children’s bladder problems, such as a doctor, physiotherapist or continence nurse advisor. They can help children with their bed-wetting from when the child is about six years of age. Before this time it can sometimes be hard to get the child to be helpful. However, in some cases it might be wise to seek help sooner, such as when:

  • the child who has been dry suddenly starts wetting at night;
  • the wetting is frequent after school age;
  • the wetting bothers the child or makes them upset or angry; or
  • the child wants to become dry.



  • 一直沒有遺尿的兒童突然開始在夜晚尿床;
  • 學齡後頻繁尿床;
  • 尿床令兒童感到困擾、令他們難過或生氣;或者
  • 尿床的兒童不想再遺尿。

Can bladder control through the day be a problem?

Some children who wet the bed at night also have problems with how their bladder works through the day. They may go to the toilet too few or too many times, need to rush to the toilet in a hurry, have trouble emptying out all the urine or have bowel problems. Unless the child has wet underwear, families often do not know about these other bladder and bowel control problems. New day-time wetting by a child who is toilet trained should be discussed with a doctor.



What can be done about bed-wetting?

Many children do stop wetting in their own time with no help. Most often, if wetting is still very frequent after the age of eight or nine years, the problem does not get better by itself. There are many ways to treat bed-wetting. A health professional will begin by checking the child to make sure there are no physical causes and to find out how their bladder works through the day. Then, there are a few ways to treat bed-wetting that are most often used:

  • Night alarms that go off when the child wets the bed. These work by teaching the child to wake up to the feeling of a full bladder. The alarm is used either on the bed or in the child’s underpants. The results are best when the child wants to be dry, wets very often, has help from a parent through the night, and uses the alarm every night for several months. Some children become dry using an alarm but later start to wet again. Alarms can work again after this relapse.
  • Drugs that change how active the bladder is or cut down how much urine is made through the night can be prescribed by a doctor. These drugs can be used to help the bladder work better at night. Drugs alone don’t often cure bed-wetting. Bladder function must be improved or bed-wetting may come back when the drug is stopped.



  • 夜間鬧鐘會在兒童平常尿床時響起。這是透過訓練兒童在感覺膀胱漲滿時醒來而發揮作用。將鬧鐘放在床上或兒童的內褲裏。用鬧鐘效果最好的情況是:兒童自己不想再遺尿、經常性遺尿,以及父母在夜間幫助叫醒。鬧鐘要每晚使用,連續幾個月。有一些兒童在使用鬧鐘之後不再遺尿,但後來又再次尿床。復發後使用鬧鐘仍然有效。
  • 藥物改變膀胱興奮程度或減少夜間產尿量,可由醫生開處方。這些藥物可以用來幫助膀胱在夜間更好地運作。但只靠藥物通常不能治癒尿床,還必須改善膀胱功能,否則當停止用藥時尿床可能會復發。

What can parents do?

  • Seek help from a health professional with special training in children’s bladder problems, such as a doctor, physiotherapist or continence nurse advisor.
  • Watch for constipation as this can make the bladder problem worse. Seek medical help if it is an ongoing problem.
  • If your child is using a bed-wetting alarm, get up when it goes off and help to wake them up and change their clothes or sheet. Make sure there is enough light at night so it is easy to get to the toilet.

There are some things which do NOT help:

  • DO NOT punish for wet beds.
  • DO NOT shame the child in front of friends or family.
  • DO NOT lift the child at night to toilet them. This may cut down on some wet beds, but it does not help the child learn to be dry.
  • DO NOT try to fix bed-wetting when other family members are going through a stressful time.


  • 向在兒童排尿失常方面受過特別訓練的醫護專業人士尋求幫助,如醫生,理療師或排便科護士顧問。
  • 告訴孩子他們的身體如何運作。
  • 留意孩子是否有便秘,因為便秘可令排尿問題更嚴重。如有持續便秘就要尋求醫療幫助。
  • 如果你的孩子使用尿床鬧鐘,當鬧鐘響時,你也要起床叫醒孩子,並幫助換衣服或床單。要確保夜晚有足夠燈光令上廁所較容易。


  • 不要因為尿床而進行懲罰。
  • 不要在朋友或家人面前羞辱孩子。
  • 不要在夜晚給孩子把尿。這可能會減少尿床的次數,但對孩子學習不再遺尿沒有幫助。
  • 不要在其他家庭成員正在承受重大壓力的時期嘗試解決尿床問題。
