What Age Should Kids Be Dry At Night?
Just remember, most children can control their bowels before their bladder. It usually takes a little longer for children to learn to stay dry throughout the night.
The brain-to-bladder connection that allows a child to wake up and hold urine overnight can take years to develop.
Although most learn this between the ages of 3 and 5, bedwetting is still common in children ages 5 to 7, and it’s important to remember that children develop at their own pace.
In fact, most kids are ready for nighttime potty training before parents typically realize, so watching for readiness signs is key.
The vast majority of children eventually stop wetting the bed as their bodies mature. However, some children may not be developmentally ready to stay dry in bed at night.
Why Is Night Potty Training So Hard?
Nighttime potty training is a longer process because it relies on a child’s physical and hormonal development, not just conscious learning. This involves:
- Hormonal development: The body needs to produce enough of the hormone vasopressin, which reduces nighttime urine production.
- Bladder and brain maturity: The development of a child’s bladder is crucial for nighttime dryness. The brain needs to develop the ability to send and receive signals from a full bladder, and the child’s bladder needs to be large enough to hold urine all night.
- Some children may have a small bladder, which can make it harder for them to stay dry overnight.
- Genetics: Genetics can play a role as well. If parents or other family members experienced bedwetting beyond the typical age, a child may be genetically predisposed to nocturnal enuresis, the medical term for bedwetting. 1
- Nighttime dryness is a developmental milestone that depends on several factors, including the maturity of a child’s bladder and their ability to wake up when they feel the need to urinate.
- Some children may be in a deep sleep, making it harder for them to recognize and respond to the urge to pee during the night.
- Common triggers such as stress, illness, or changes in routine can sometimes cause a child who was previously dry at night to start wetting the bed again.
Why Nighttime Toilet Training Is Different From Daytime Training?
- Consciousness: During the day, a child is awake and can respond immediately to a physical urge.
- Conscious vs. unconscious response: At night, the process is involuntary. A child who is asleep cannot consciously “remember” to go to the bathroom.
- Developmental timeline: Many children achieve daytime dryness between ages 3 and 5 but can take longer for nighttime dryness. A child should be consistently dry during the day before beginning nighttime training.
- Daytime potty training is usually mastered before nighttime dryness, and achieving daytime potty training is an important step before focusing on nighttime training.
How Long Does Nighttime Potty Training Take?
Nighttime dryness often lags behind daytime toileting skills. Many kids who are fully potty trained during the day continue to experience nighttime wetting for months or even years.
10 Tips On How To Toilet Train At Night
Nighttime potty training can be one of the more challenging aspects of the potty training process, but with patience and the right strategies, it is entirely achievable.
Here are ten helpful tips to guide you through how to toilet train at night effectively:
Establish a Consistent Bedtime Routine
A calming and predictable bedtime routine can help your child relax and prepare for sleep. Include activities like brushing teeth, reading a story, and using the potty right before bed.
Limit Fluids Before Bedtime
To reduce the likelihood of accidents, try to limit your child’s fluid intake about two hours before bedtime. A good rule is to offer most drinks earlier in the day and avoid large amounts of fluids close to bedtime. 2
Encourage a “Double Void” Before Bed
Have your child use the potty twice within 30 minutes before going to sleep—once as part of their bedtime routine and once immediately before getting into bed. This helps empty the bladder as much as possible, reducing the chance of wetting the bed.
Use Training Pants or Pull-Ups Strategically
While some children benefit from wearing a pull up during the transition, others do better without them to increase their awareness of accidents.
Create Easy Access to the Potty
Make sure your child can easily get to the bathroom during the night. Consider placing a smaller potty in your child’s bedroom if the bathroom is far away. This encourages independence and reduces fear of the dark.
Protect the Mattress
Accidents are common during nighttime potty training. Use mattress protectors and waterproof pads to help manage the aftermath of an accident, making clean-up easier and keeping the sleeping environment comfortable.
Celebrate successes and avoid punishing accidents
Positive reinforcement, such as praise or small rewards, can motivate your child to stay dry at night.
Use Moisture-Activated Alarm
Consider a moisture-activated alarm if bedwetting persists. 3
Stay Positive and Patient
If your child wakes up wet, calmly help them change and encourage them to use the potty before going back to sleep.
Use Nightlights
Using nightlights to illuminate the path to the bathroom helps children feel safe and confident at night.
As boys get older, they often switch from sitting to pee at night to learning how to pee standing. 4
This transition to pee standing can be introduced once they are comfortable and confident, but starting with sitting can help reduce mess and make nighttime trips safer.
When Potty Training Do You Use Diapers At Night?
Using diapers at night during potty training is a common consideration for many parents. Whether to use nighttime diapers or pull-ups largely depends on your child’s readiness and your approach to nighttime potty training.
- Common Approach: Many parents keep their child in diapers or pull-ups during sleep until the child consistently wakes up dry. This provides security and helps prevent messes, especially early in night training.
Studies suggest that starting nighttime potty training earlier and reducing diaper use can help your child develop the ability to stay dry overnight sooner. 5
Diapers and pull-ups are highly absorbent, which may reduce a child’s awareness of needing to urinate during sleep, potentially delaying bladder control development at night.
How Do You Know When Your Child Is Ready To Be Dry At Night?
Many experts recommend assessing your child’s readiness before deciding to start night time toilet training.
Signs that a child may be ready to stop using diapers at night include:
- Waking up with a dry diaper for several consecutive mornings
- Staying dry for longer stretches during naps or overnight
- Showing interest in wearing underwear at night
Nighttime potty training
Children who start potty training later often train more quickly due to increased physical, cognitive, and emotional readiness.
Should I Wake My Child Up At Night To Pee?
Waking or lifting your child regularly to pee isn’t recommended for long-term dryness. It can disrupt their natural ability to wake when their bladder is full, which is key for lasting success.
However, some parents do wake their child—usually about 3 hours after they fall asleep—as a short-term fix to reduce wet sheets during the transition away from diapers.
Waking or lifting should be temporary, to help your child develop their own waking reflex and bladder control over time. 6
Regularly waking or lifting children to pee will not promote long-term dryness.
Leading health authorities only advised it as a short-term, practical step for managing bedwetting.
When To Worry About Overnight Potty Training?
You should consider speaking with a healthcare provider in the following situations:
- Age and frequency: Your child is over 5 years old and still wets the bed regularly, such as more than once a month.
- Sudden onset: Your child was dry for at least six months and has suddenly started wetting the bed again.
Consult a healthcare provider if bedwetting continues after age 5 or 6.
These signs can sometimes indicate an underlying medical condition or stress, so it is important to consult a doctor to rule out any issues.

Frequently asked Questions
Is night time bed wetting hormonal?
We all produce vasopressin—a hormone that signals our kidneys to reduce urine production during sleep. Some children haven’t started making enough of this hormone yet, so their kidneys produce more diluted urine than their bladder can hold.
What deficiency causes bed wetting?
Evidence has revealed that vitamin D and omega-3 insufficiency are risk factors for enuresis so their supplementation may be a potential solution for this disorder. Recent studies have shown that vitamin D deficiency can be the reason for nocturnal enuresis in children.
Is bedwetting linked to ADHD?
Bedwetting is common among children with ADHD. The medical term for bedwetting is enuresis. Studies show that about 28–32% of individuals with ADHD experience enuresis, and another study found that up to 40% of children with ADHD may have this issue.
Why is my potty trained toddler regressing at night?
This setback is quite typical and a normal part of the potty training journey. It may occur due to various factors, such as changes in routine or surroundings, emotional stress, or even seeking additional attention. The important thing to keep in mind is that this phase is generally temporary and part of the overall learning process. Avoid scolding or teasing a child for accidents to prevent anxiety and hinder progress.
How long can a potty training regression last?
A potty training regression typically lasts from a few days to a few weeks, but can sometimes last longer depending on the child and the cause. Most regressions are temporary and resolve with patience and encouragement, but if a regression lasts for a month or more, it’s a good idea to speak with your kid’s pediatrician.
