Nighttime Potty Training: When to Start and Tips to Help the Process

Nighttime potty training can feel daunting, especially when your child has mastered potty training in the daytime but still wakes up wet. This is completely normal! Overnight dryness is generally influenced by brain-bladder signaling, along with practical habits your child can develop while awake. The goal isn’t perfection overnight—it’s a plan that protects sleep, builds confidence, and reduces accidents.

Signs your child may be ready for potty training at night:

• Dry or only slightly damp mornings for several days

• Dry naps or waiting until early morning to pee

• Asking to wear underwear or use the potty at night.

Next, we’ll cover simple routines and setup tweaks that make nights easier for everyone.

Daytime vs. Nighttime Potty Training

Around age 2 is when children often start potty training, though some are ready earlier and others need a little more time. Daytime toilet training involves your little one recognizing the urge to pee and getting to the potty or toilet on their own or with the help of a trusted adult. By the end of the process, your child will be able to use the toilet and no longer rely on diapers during the day.

Nighttime potty training comes later, after daytime toilet training is successful. It’s important to know that your toddler will most likely still need to use diapers at night and possibly during naptime as you work on daytime potty training. 

Keep in mind that the timeline for nighttime potty training success varies from child to child, and that some kids need more time to master overnight dryness; bowel control usually develops early on. Some children aren't able to stay dry at night until they’re around 5 or 6 years old, and that’s OK.

When to Start Nighttime Potty Training?

When to potty train at night will depend on your toddler. Although you can incorporate some nighttime potty-training techniques into daytime training, it’s best to wait until your child is regularly using the toilet before focusing on staying dry overnight. 

Children develop at different paces, so there’s no single nighttime potty training age. However, if your child begins potty training at about 2 years old, they might be ready to start working toward nighttime dryness by age 3.

Is Nighttime Potty Training Possible?

In a word, yes! As a parent, it’s probably challenging to wrap your head around potty training at night when your child is sound asleep, but nighttime potty training is not only possible, but it’s also doable. Here are a few things to keep in mind:

• Bowel control. Your toddler probably won’t experience overnight bowel movements, as children tend to master bowel control during daytime potty training. But, of course, every child is different.

• Bladder control. If you’re wondering about the reasons for bedwetting after your child is potty-trained, remember, it’s completely normal for this to happen. It takes time for the bladder to mature and for the brain to be able to send signals that it’s time to wake up from sleep to pee. This physiological development isn’t typically complete until 6 years of age. That's why nighttime bedwetting (enuresis), even after being potty trained, is common in children up until 5 or 6 years.

• Waking up. Some parents wonder if waking their child up from sleep should be part of potty training at night. It’s best to let your toddler develop the ability to wake up on their own when needing to pee. However, if your child is wetting the bed at night after age 5, you could consult their healthcare provider. In some cases, the provider may recommend using a bed-wetting alarm device, which automatically goes off when moisture is detected and helps make the linkage between waking up and needing to pee.

What Age to Stop Using Diapers at Night?

Many parents wonder, “When do kids stop wearing diapers?”—especially at bedtime. The truth is, nighttime dryness often comes later than daytime potty training.

As mentioned earlier, daytime bladder control is often mastered first, with nighttime control developing months—or even years—later. Bedwetting can be typical up to age 5 and beyond. 

So, if you’re asking, “When do babies stop wearing diapers at night?” there isn’t one “right” age. Many children stop wearing diapers at night between the ages of 3 and 7, but every child develops at their own pace.

You might notice signs your child is ready to go without nighttime diapers, such as:

• Waking up dry several mornings in a row

• Staying dry during naps

• Showing awareness of a full bladder.

Nighttime dryness often depends on physical development, including hormone levels that reduce urine production at night and a child’s ability to wake from sleep when their bladder is full. Remember that bedwetting is not something your child can control or “try harder” to fix. Reassurance and patience are key to helping your child. 

In the meantime, potty training pants can help protect bedding while your child builds confidence and independence.

How to Toilet Train at Night

If you’re wondering how to nighttime potty train, it helps to remember that nighttime dryness is different from daytime potty training. Readiness matters more than age.

Your child may be ready for nighttime potty training if they:

• stay dry during naps

• wake up dry several mornings in a row

• are consistently successful with daytime toilet training

• show interest in wearing underwear overnight.

If you’re researching how to potty train a 3-year-old or a 4-year-old at night, know that accidents at these ages are still completely normal.

Nighttime bladder control improves as:

• the bladder grows and can hold more urine

• the brain responds to bladder signals during sleep

• the body produces more antidiuretic hormone (ADH), which reduces urine production at night.

Because this process is developmental, learning how to potty train overnight is often about creating supportive routines while giving your child’s body time to mature.

13 Nighttime Toilet Training Tips

Once your child is showing signs of readiness, these nighttime potty training tips may help support success. Think of these as practical tools to go along with the developmental process:

How Long Does It Take to Potty Train at Night?

The timing for night potty training varies. According to the American Academy of Pediatrics (AAP), nighttime dryness can take months—or even years—after daytime potty training is complete. It’s common for children to still wet the bed at age 5, and many outgrow it naturally over time. Nighttime bladder control depends on physical development, not effort or practice alone.

So when asking, “How long does night potty training take?” it may help to think of it as a gradual process. Some children stay dry within a few weeks of starting nighttime potty training, while others need longer for their bladder capacity and sleep-wake response to mature.

If your child continues to wet the bed regularly after age 6, consult your child’s healthcare provider for guidance.

When to Consult Your Child’s Healthcare Provider

Managing bed-wetting is a key part of potty training at night; note that some children may be dealing with this issue on occasion until adolescence. Keep the following in mind:

• Accidents are common for children during daytime or nighttime potty training

• After six months of potty training, accidents may decrease, but can still occur, especially at nighttime

• Bed-wetting commonly persists for up to one year after starting nighttime potty training.

Contact your child’s healthcare provider if your little one is older than 6 and still wetting the bed at night consistently despite nighttime potty-training efforts. They may just need a little more time with potty training. The provider can look for any signs of issues and offer advice or treatment options if necessary.

The Bottom Line

Children develop and reach success at their own unique rates, and that holds true for completing nighttime potty training. Although some children achieve dry nights faster than others, it’s common for bed-wetting to occur regularly up to 5 years old and occasionally into adolescence. 

Potty training at night is a gradual process that requires patience. You must wait for your child's bladder to mature and for their brain to learn to send signals to wake up when it's time to go to the bathroom. Children don’t usually achieve this until about 6 years old, so your child is almost guaranteed to experience accidents throughout nighttime potty training—and that’s OK. 

The best tips on how to potty train overnight include staying patient, positive, and offering encouragement. Some additional tips and tricks include the following: 

• Be prepared for accidents by using a plastic mattress protector and having a clean sheet and a change of clothes within easy reach.

• Create bedtime and morning routines that include using the toilet right before bed and immediately upon waking.

• Make the toilet accessible by putting night-lights in your child’s bedroom, the hallway, and the bathroom.

• Use training pants until your child is dry for multiple nights in a row for numerous weeks, and then switch to “big kid” underwear for a feeling of achievement!

Contact your child’s healthcare provider if they’re still experiencing bed-wetting at age 6. Most likely, your child just needs a little extra time to reach this nighttime potty-training milestone, but their provider can help rule out any problems, offer advice, and suggest treatments if required.

Even wet nights aren’t so bad when you can reward yourself with every purchase of training pants (or wipes or diapers) with the Pampers Rewards app.
