If your child is having trouble with bedwetting overnight, you may be feeling frustrated and unsure how to help. Every time it happens, you may wonder, “Is there an end in sight?”

First, know this: They’re not alone. An estimated 15% of children in the U.S. still wet the bed at age 5, known as nocturnal enuresis. And most kids outgrow bedwetting on their own, says pediatric urologist Jessica Hannick, MD
But some lifestyle and behavioral habits may help — including using a device called a bedwetting alarm, which works wonders for some families
Dr. Hannick explains what bedwetting alarms are, how they work and when they may be worth trying
What is a bedwetting alarm?
Bedwetting alarms (aka enuresis alarms or moisture alarms) are devices with moisture sensors. They go under a mattress pad or clip to your child’s underwear overnight. If your child wets the bed, the moisture from their urine triggers a loud alarm to wake you both
In the beginning, though, the alarm often only wakes the parent, while the child continues to sleep deeply. So, you may have to get up and rouse them
“I encourage parents to wake the child up and take them to the bathroom to sit on the toilet and try to pee again, and then wash their face or brush their teeth to make sure they’re truly awake,” Dr. Hannick explains. “This encourages their brain to gain alertness to the messages their bladder is trying to send.”
In other words, continually waking up afterthey pee actually trains their brain to wake them up beforethey pee

The goal is that, over time, all of those post-accident wakeups will eventually help your child’s brain and bladder start to make the connection to wake them up beforean accident — ultimately, putting an end to bedwetting
To reiterate, bedwetting alarms are triggered by moisture afteryour child has an overnight accident. “This can be confusing to parents, who commonly think the alarm will go off before an accident occurs,” Dr. Hannick notes
Do bedwetting alarms work?
Once you start using a bedwetting alarm, it can take about three months for your child to learn to wake up on their own to the sensation of a recent accident — and later, of a full bladder
But it doesn’t work for everyone. Bedwetting alarms aren’t usually helpful for kids who don’t yet have any interest in being dry
“In my experience, bedwetting alarms work best for children ages 7 and up who are independently motivated to get dry and whose parents can stay on a consistent routine with the alarm,” Dr. Hannick shares
They may also not be a good fit if you have other kids in the house who may wake up when the alarm goes off
“It’s not always logistically feasible, and it can be exhausting for the parents,” she acknowledges
How is it different from a regular alarm?
So, why try a bedwetting alarm at all? Why not just use a regular alarm clock to wake up your child in the middle of the night to pee?
“Setting a random alarm doesn’t correlate with what’s going on in your child’s bladder,” Dr. Hannick explains. “They may have had an accident minutes or hours ago or not even need to pee. So, it’s not really training the brain properly.”
It’s the same reason she encourages parents not to wake their kids up in the middle of the night to use the bathroom: You may think you’re safeguarding them from an overnight accident, but it doesn’t help their bladder and brain learn how to communicate properly
What else to do for bedwetting
Try lifestyle and habit tweaks first before you turn to a bedwetting alarm
“Most of the time, healthcare providers recommend starting with behavioral changes,” Dr. Hannick says. “If those don’t work, depending on your child’s age and motivation to get dry, you might move on to discussing a bed alarm or medication.”
These tips can also help your child outgrow bedwetting
- Don’t shame them.Motivation works better than blame (and it’s kinder, too). “Avoid negative emotions, like guilt or shame toward your child’s bedwetting,” Dr Hannick urges. “Punishment only makes stress and self-esteem issues worse.”
- Scale back on beverages. A glass of water before bed can be tempting, but it only raises the chances that your child will have to pee overnight. Kids should aim to stop drinking liquids one to two hours before bedtime.
- Pee before bed.Encourage your child to use the bathroom right before they go to bed each night. “Even if they don’t feel like they have to go, they should try to ‘empty the tank’ so it can fill overnight,” Dr. Hannick advises.
- Address poop problems.The bladder and bowels are closely connected, so constipation can contribute to bedwetting. To promote soft poops, focus on hydration and a fiber-rich diet.
- Encourage good sleep.Following a consistent nighttime routine and healthy sleep habits helps regulate your child’s sleep, which may help with bedwetting.

When to talk to a doctor about bedwetting
If your child is struggling with bedwetting, it’s always OK to talk to their doctor about it. They can talk you through lifestyle strategies that may help — and they may also want to check your child for any underlying medical issues
Conditions that can contribute to bedwetting include:
- Urinary tract infections
- Mental health concerns
- Neurodivergence
- Hormonal imbalances
- Chronic medical conditions, including diabetes
You should also always talk to your child’s provider if they:
- Experience pain or burning with urination
- Are newly having accidents
- Drink lots of fluids but always seem thirsty
- Need to pee often but have lots of pee every time
- Snore loudly or seem to have pauses in breathing at night
- Have numbness, pain or tingling in their legs or feet
- Have poop accidents or frequent underwear stains
All of these can be signs of an underlying medical condition
“Most of the time, bedwetting is developmental,” Dr. Hannick reiterates. “But if it’s due to something else, diagnosis and treatment are key.”
