Nighttime Potty Training: A Different Process
Why nighttime dryness comes later—and how to approach it.
Daytime trained but still wet at night? That's completely normal. Nighttime dryness is a separate developmental milestone that often comes much later—and it's less about training and more about biology.
Why Nighttime Is Different
It's About Biology, Not Behavior
Daytime training is about recognizing signals and getting to the potty. Nighttime dryness requires: - Bladder capacity to hold urine all night - A brain that wakes them (or holds urine) when the bladder is full - Hormones that reduce urine production at night (ADH)
These are developmental. You can't "train" them into existence.
The Brain Has to Mature
The brain-bladder connection that wakes a child (or holds urine) during sleep develops on its own timeline. Some kids have it by 3; others not until 7 or 8.
Genetics Play a Role
Bedwetting runs in families. If one parent wet the bed late, their child is more likely to as well. If both parents did, the odds increase significantly.
When to Expect Nighttime Dryness
- Most children are reliably dry at night by age 5-7 - Many aren't dry until later - Bedwetting up to age 7 is considered developmentally normal - Even after 7, it's common and usually resolves
Signs of Readiness
Your child may be ready to try nights without diapers if: - Diaper is frequently dry in the morning - They wake up to pee at night - They stay dry during long naps - They're bothered by wet diapers at night
If the diaper is wet every morning, they're not ready—their body isn't there yet.
Approaches
Waiting (The Most Common Approach)
Simply wait until they show signs of readiness. Use overnight diapers or pull-ups without shame.
Pros: No stress, no wet sheets, lets biology take its course. Cons: May feel like "not doing anything."
Nighttime Training (If Showing Readiness)
If diapers are often dry: - Reduce liquids before bed - Potty right before bed - Try underwear with a waterproof mattress cover - Accept that accidents will happen
Pros: Reinforces the transition, takes advantage of readiness. Cons: Wet sheets, disrupted sleep.
Wake to Pee
Waking your child to pee before you go to bed (10-11pm) can help them stay dry.
Pros: Can reduce wet nights. Cons: Disrupts sleep, doesn't teach independent waking.
Bedwetting Alarms (For Older Kids)
For children 6+ who are motivated and bedwetting persists, alarms can help train the brain to wake. These take commitment (2-3 months) but have good success rates.
What NOT to Do
Don't Restrict Fluids Excessively
Adequate hydration matters. Mild reduction before bed is fine, but don't make them thirsty.
Don't Punish Accidents
They can't control this. Punishment creates shame without changing anything.
Don't Shame Them
They're not being lazy or babyish. Their body isn't ready yet. Shame damages self-esteem and doesn't help.
Don't Compare to Siblings or Peers
Every child's timeline is different.
Managing Nighttime Accidents
Protect the Mattress
A waterproof mattress protector is essential. Easier to wash sheets than replace mattresses.
Double-Layer the Bed
Mattress protector → fitted sheet → another mattress protector → another fitted sheet. When there's an accident, just strip the top layer.
Keep Cleanup Supplies Ready
Clean pajamas, wipes, and clean bedding accessible for middle-of-night changes.
Stay Calm
A tired "oops, let's get you changed" is appropriate. A frustrated lecture at 3am isn't helpful.
Let Older Kids Help
School-age kids can help change their own sheets. This isn't punishment—it's appropriate responsibility and reduces shame by giving them agency.
When to See a Doctor
- Child is 7+ and consistently wetting - Child was dry for 6+ months and started wetting again - Wetting is accompanied by other symptoms (pain, unusual thirst, snoring) - Child is distressed about the bedwetting - You want to explore medical options
Your pediatrician can rule out physical causes and discuss options like medication or bedwetting alarms.
The Big Picture
Nighttime dryness will come. For most kids, it resolves on its own by school age. For others, it takes longer—and that's okay.
Your job is to manage it with as little stress as possible while protecting their self-esteem. This isn't a training problem—it's a waiting game.
