Though peeing through diapers at night is not a special problem in babies, it’s often annoying for families. Besides wetting the socks, pajamas, and sheets with urine, overcapacity diapers wake the baby up with a soggy, cold call.

It causes babies and parents to say “good morning” earlier than normal, which is not so happy and makes the parents do more daily laundry. So, it’s crucial to find out how to keep your baby from peeing through his diaper at night.

This problem won’t be challenging with the 11 proven ways below. Keep reading to stop overnight diaper leaking gently.

Why Does Your Baby Keep Peeing Through His Diaper at Night?

Here’re the six most common reasons your child pee through his diaper when sleeping. Let’s get a peek at each reason individually.

1. The Baby’s Body Is Short of Antidiuretic Hormone

ADH (antidiuretic hormone) is a hormone present in a human’s body, telling us to reduce urine production.

ADH levels in adults increase overnight. Thus, we don’t constantly run to the restroom during the nighttime. Meanwhile, ADH levels in babies are generally lower, meaning urine production will stay high overnight.

If your newborn is often a full bladder and has low ADH levels, he’s likely to pee through his diaper when sleeping.

2. How The Baby’s Body Processes Liquids

Toddlers may start leaking through diapers after reaching six months, and this issue can continue until they pass the toddler years. With time, their bladders grow, too, meaning they can store more liquid and produce more urine that leaks out before morning.

3. Drinks Too Much Liquid

You should pay attention to restricting how much your baby can drink before bed.

Consuming enough fluids is essential for babies to be healthy and hydrated. Some newborns also use liquid, like formula or breast milk, as their primary nutrition source.

However, if you see a diaper soaked with urine every morning, it’s necessary to change the amount of liquid your toddler drinks before night.

4. Wriggles A Lot At Night

Many toddlers sleep without staying in place but wiggle and move a lot, even though you have previously positioned them.

You don’t want to sometimes wake up at midnight to check if your child has turned around. But if you let him wriggle around, it will strain the diaper, allowing leaks and gaps to occur.

5. Sleeps On His Stomach

Tummy sleeping is another cause of the leaking through the diaper overnight.

Sleeping on his stomach reduces diaper absorbency and makes it fails to hold all the urine, causing the leaks to flow onto his tummy or back.

This habit will put different areas on the baby’s pants under pressure, increasing the odds of the toddler peeing through his pants.

6. The Wrong Diaper Size

The size and brand you use for your baby during the daytime aren’t necessarily suitable for them at night.

If the diaper leaking issue occurs every night, it is advisable to size up diapers to ensure dryness and comfort. Because larger-sized diapers have a higher degree of absorbency to store the excess urine seeping out.

The incorrect diaper size is also one of the leading causes of diaper blowouts.

How to Stop Overnight Diaper Leaks

Although you can’t stop leaks completely, it’s possible to reduce the amount of leaking. Below are the most effective solutions to help your baby sleep through the night without peeing through diapers.

1. Change Your Baby’s Diaper Right Before Bed

The first tip is to change a new diaper. Fresh diapers will offer a comfortable feeling and help your baby fall asleep easier.

If your little one is a tight sleeper, which implies that you can switch their positions without waking them up, try to change them one more time before hitting the sack.

If the baby is a boy, point the private part downward for him before bed so that he will not pee upward.

2. Adjust the Diaper

Altering the diapers a bit can help prevent nighttime urine leaking. We advise you to pull the diapers slightly forward to make them stay higher on the child’s stomach, particularly overnight diapers. This practice helps the material absorb more liquid in the front because leaks usually occur there.

You should also adjust the straps slightly, taping them slightly upward instead of directly across the toddler’s hips. That will put these areas under more pressure and help soak up more liquid, particularly if the toddler has a heavy bladder.

3. Add Diaper Liners

In essence, diaper liners function as padded liners that you put into your baby’s diapers. It’s possible to adjust the liner’s placement for girl or boy needs. These liners can store around eight ounces of fluid and keep babies feeling dry at night.

We recommend buying disposable products that you can throw away in the morning. They apply perfectly to toddlers and save parents a small amount monthly if used at nighttime.

Besides, parents don’t have to spend much time changing and washing sheets and will have a more restful night.

4. Use Overnight Diapers

Several brands have tailor-designed products specifically for night use, which are more absorbent, tougher, and can tolerate a night’s amount of urine better. All toddlers are different; the same goes for diaper types.

If you’re suffering from constant overnight diaper leaks, try switching types to see if it works. Overnight diapers are more costly than typical ones, yet you get what you pay for. You’ll use these special diapers at night only, so a package can last longer.

5. Use a Larger Diaper at Night

The current size may be fine during the daytime, yet a larger-sized one would be a great solution to prevent leaking overnight.

Regular diapers can work without leaking since parents can change their babies more often. They also fit snugly, which is critical when babies are mobile and awake.

However, larger-sized diapers work not merely because the child is less mobile. It’s also because they can soak up more liquid than the regular size.

Still, ensure the large diapers fit snugly before bed because areas around the baby’s thighs can leak.

6. Change Diaper Brands

Parents barely think of changing a new diaper brand, but this tip sometimes works. There are endless options to choose from, yet we suggest going for the highly-rated disposable products if you want to search for a different brand.

When switching brands, purchase a small package to test first, and size it up if the product works for you and your little one.

If your baby urinates frequently or is a dense wetter, look for heavy-duty, thick diapers. However, you need to be mindful if your children have sensitive skin. Ensure to make a wise buying decision, purchasing only products that don’t cause rash and are comfortable.

7. Use Cloth Diapers

Cloth diapers may appear a bit old-fashioned or odd, particularly for parents who get used to using disposable diapers only. And it seems to take a lot of time and work.

Yet, they are probably the simplest way to stop leaking through diapers at night. You can stick to disposable diapers in the daytime and switch to cloth ones at nighttime.

These cloth diapers are excellent for nighttime leakage since parents can easily control absorbency. If the toddler still pees through them, try using thicker ones. The more the inserts, the greater the absorbency.

8. Use Peejamas Overnight

Indeed, Peejamas is not the most effective solution to this problem. Yet, we suggest this for children who have just started or been in the middle of potty training. It will be easier to tackle bladder control with these children.

There is a highly absorbent cloth at the bottom of a Peejama. You pull it on like a pair of pajama bottoms and undies.

This special product can store about ten ounces of liquid or approximately three pees a night. A regular toddler bladder may store 3-5 ounces, while a regular baby bladder may store 1-2 ounces.

Why don’t you try replacing an overnight diaper with Peejamas after the above methods fail? They will help your children hold their urine through the night.

9. Train Back Sleeping

Tummy sleepers will experience leaking more often than those sleeping on their backs. Extra strain on the diapers’ front side leads to more issues with gaps and leaks. Thus, we highly suggest training your little one to sleep on their back gradually.

Back sleeping helps reduce baths and laundry after a soaking morning and is a healthier sleep habit, particularly when your child is younger.

10. Reduce Liquids At Night

Parents often let their children munch on their sippy cups or bottles before bed, resulting in issues because their tiny bladders can’t hold that much water overnight.

Yet, it doesn’t mean you deter the little one from consuming liquids since they need the formula. We never recommend keeping your toddlers away from water, but let them consume water three or four hours before hitting the hay if they’re thirsty.

That means no sports drinks, flavored water, or juice. If something tastes delicious, babies will crave its flavor more, not quenching their thirst.

Besides, sugary beverages are a diuretic that increases urine production. If you allow the child to drink only water before bed, they tend to drink it only when thirsty, minimizing the chance of overnight wetting.

11. Provide Extra Protection

This last hack is straightforward and amazingly helpful in preventing overnight diaper soaking. That is to provide the diaper with additional protection.

For example:

  • Put fleece shorts inside the pajamas, over the fresh diaper, before dressing the little one in pajamas. Though the baby may pee through the first layer, the shorts will help absorb wetness.
  • You can use two diapers. Dress the baby in a typical diaper first. After that, add another larger-sized one on top.

What To Do If Your Baby Continues Overnight Diaper Leaking?

The above methods should work in most cases. However, if it’s impossible to stop your baby from peeing through diapers every night, try the tips below.

1. Place A Waterproof Blanket or Pad Under The Bed

You’re using a non-toxic, high-quality crib mattress under your toddler bed or crib, and you don’t want urine to soak in and hurt it.

If you do not want to switch to another more affordable one, we advise you to buy a waterproof, non-toxic cover. This item will make life much easier.

For example, Naturepedic’s version is our cup of tea. It doesn’t use toxic chemicals to gain waterproofing and is safe for babies’ skin.

The best idea is to buy dryable and machine-washable pads, which can prevent any urine from leaking through the sheets and into the expensive mattress and encourage bacteria and mold growth.

2. Layer The Baby’s Mattress

This tip works for any mattress and crib. When compiling your toddler bed, spread the sheet and mattress pad, then lay another sheet and mattress pad down, covering the first two layers.

If your little one pees through the diaper, pajama, and sheet at midnight, you can remove the top mattress and sheet quickly, change the pants, then place them back down.

We strongly recommend buying plastic-backed, specially-made bed covers if you have a generous budget. They’re more straightforward to throw into the dryer and washer and won’t hurt your mattress.

They do a great job drawing down the moisture, so your little one won’t lay in the middle of urine.

3. Skip Pajamas or Bed Sheets for a While

Does your living place have warm weather? If yes, you can ensure that the toddler won’t be cold at night. So, it’s possible to let him hit the hay without pajamas. This way, changing overnight will be easier, and you can limit laundry if he pees through diapers.

Bed sheets are also removable for a while. You can wipe off the mattress pad when changing the pants and clean it in the morning.

4. Buy A Washable Mattress

Mattress pads can be incredibly gross if your baby pees through diapers through them from one night to another. Thus, we suggest looking for a washable mattress that is 100% safe for machine washing.


Leaky diapers can turn a restful night into a nightmare with chaotic clutter for parents. Fortunately, you can avoid sleeplessness and deter it from happening with some actionable tips.
