My baby keeps peeing through the diaper at night. What do I do? 

If you are really tired of waking up in the middle of every night to change wet sheets and clothes, looking for practical ways to prevent diaper leaks at night is definitely on your priority list. 

I struggled with leaky overnight diapers for a long time, and as you know, it is so frustrating. 

After all that changing, your little baby will be wide awake and there is no doubt, you are going to have to start a nighttime routine all over again!

We all wish for that magical 10hr+ sleep at night. Once you put your baby to bed, the last thing you want is for them to wake up crying because they are soaking wet. 

It is unnecessary and definitely preventable. 

Say bye-bye to sleep disruption and say hello to more peaceful nights with these practical tips to stop overnight leaky diapers.

Why Do Diapers Leak At Night?

Moms are continuously worried that their baby’s diaper keeps leaking at night and often look for tips to stop this. 

Overnight diaper leaks are caused by different factors. 

Let us have a look at some of them

A Lot Of Fluid Intake

A baby who drinks a lot of milk or water during the day will undoubtedly pee a lot. 

They need to flush out that liquid and a good amount of urine is always good in this case, it means your baby is healthy.

Limiting fluids to prevent diaper leaks is not the best solution, and is not recommended for smaller babies. It might even lead to constipation.

There are other ways to combat leaky diapers.

Taking Long To Change Diapers 

If there is a huge gap between diaper changes, leaks are bound to happen. 

Diapers need to be changed frequently at least every three hours to avoid diaper rash and skin irritation.

Incorrect Diaper Size

An oversized diaper will do a poor job when it comes to containing urine. 

A super tight fit will also not help. 

The diaper needs to have the right fit to do the right job.

The Material Used In The Diaper 

Different materials have different absorption levels. 

Diapers that are made from natural fibers like cotton, hemp, and bamboo are more absorbent, although costly. 

If you can’t spend a fortune on diapers but would give anything for leak-free nights, try using higher quality diapers made from these materials at night and regular ones during the day.

Sleeping Position

Baby sleeping on the stomach

The way your baby sleeps can cause their diapers to leak while sleeping. 

For instance, a baby who moves around a lot at night can move an ill-fitting diaper out of position, resulting in leaks. 

A baby sleeping on their tummy will press over the diaper in front and leave less room for the diaper to expand when it absorbs the urine. 

Difference Between Girls And Boys 

Putting on a diaper on your baby girl is as straightforward as making sure the straps are tight enough, the diaper is in position and the raffles straightened out on the legs.

For boys on the other end, you need to position the boy part to point down so the urine flows toward the back. 

If pointed upward, urine will flow up to the front first and make it more likely for the diaper to leak.

How To Stop Diaper Leaks At Night

Even after addressing the reason why diapers leak and doing some fixes, you are still faced with overnight diaper leaks. 

It is time to put some diaper hacks to work.

Here is how to prevent a diaper from leaking overnight.

1. Change The Diaper Just Before Baby Falls Asleep

This was my favorite hack to get my baby to sleep longer at night. I simply didn’t want them waking up from a wet diaper. 

Use the same trick to prevent diaper leaks at night. 

Changing the diaper just before you put your baby to sleep ensures your baby sleeps with a completely dry diaper and reduces the chance of it getting too full and leaking while they sleep. 

Make sure to check the diaper again before you go to bed. Don’t wake your baby to change their diaper though. 

Unless your baby is a deep sleeper, a diaper change will disrupt their sleep. So only go ahead if the diaper is indeed very full. 

Otherwise just check and estimate if it will last until when they wake up. 

If not, be prepared to wake up during the night to change them, either because they are awake from discomfort from a wet diaper or because it has leaked. 

2. No Tummy Sleeping

Sleeping on the back reduces chance of overnight diaper leaks

Babies who sleep on their tummies are more likely to have overnight diaper leaks. 

This is because when a baby is sleeping on their tummy, pee tends to travel up the diaper instead of towards the back where there is more space. 

It also doesn’t help that a tummy sleeper will obviously compress the front part of the diaper, creating less room for pee to be absorbed. 

Avoid letting your baby sleep on their stomach when they are still small. It is not recommended and not in line with safe baby sleep guidelines.

Most babies end up sleeping on their stomachs as soon as they start rolling over. Gently put your baby back in a safer sleeping position without waking them up.

3. Ditch Tight Fitting Outfits

Most babies go to bed with onesies and sometimes trousers if it’s chilly. 

Even with a proper fitting diaper, a onesie or trouser that is too tight will compress the diaper and increase the chance for a leak.

4. Make Sure The Diaper Fits Properly

An ill-fitting diaper is more likely to leak compared to a proper-fitting one. 

If your baby’s diapers fit too tightly, pee might actually squeeze out before getting a chance to be absorbed. 

The diaper should be tight enough to stay in place without having your baby feel pressed (yeah).

You should also make sure your little one’s diaper is positioned properly and not skewed. 

A ‘one bum in-one bum out’ diaper increases the chance for leaks throughout the night.

Double-check if the raffles around your baby’s legs have been straightened out. 

I’ve had a few leaks where I found that I had forgotten to fix the raffles.

5. Use A Larger Size At Night

A larger size offers more liquid absorption compared to a smaller size diaper. 

Consider going one size up for the night and put on the normal diaper during the day. 

Remember that a larger size should still fit snugly without any gaps around your baby’s waist and legs.

6. Try Overnight Diapers

Overnight diapers are more absorbent than regular ones and can keep your baby dry for up to 12 hours. 

Get the same brand your baby is using already and see how it goes.

If you are not satisfied try a different brand. These overnight diapers are hypoallergenic and free of parabens and latex, making them safe to wear on sensitive skin.

You can even go one size up from your baby’s current diaper size, provided it still fits well otherwise it will just leak as well

7. Use Diaper Extender Pads

A diaper extender sort of extends the size of your baby’s diaper and covers areas where the diaper doesn’t reach. 

If your baby is peeing through the back of the diaper or up in front, this is where you will place the diaper extender.

Similarly, if your baby keeps peeing through the side of the diaper at night, add the extender on the sides of the diaper.

These diaper extenders have saved a lot of outfits from blowouts and leaking pee. 

8. Use A Booster Pad

Booster pads are a great way to add extra protection against overnight diaper leaks. 

When placed inside a diaper, the booster pad will absorb the liquid first, and the excess will pass through to the diaper. 

Since your baby will have them on all night long, you want to get booster pads that are free from phthalates, chlorine, latex, alcohol, lotions, and fragrances. 

This will reduce the chance of your baby developing a diaper rash.

Is your baby a heavy wetter or do they tend to roll onto their side or stomach while sleeping? 

Adding a booster pad to your baby’s diaper can help you prevent diapers from leaking overnight and allow your baby to have a full night’s sleep. 

9. Change Diapers With Every Night Feed

If your baby still wakes up to feed at night, use feeding time as a chance to check on that diaper. 

If the night is still young but there is a little urine on the diaper, go ahead and change it. 

Better now than two hours later when all the sheets are wet. 

Changing the diaper after your baby feeds at night might actually help them sleep better afterward. 

A wet diaper is one of the reasons why your baby just won’t sleep. It is so easy to miss this!

After drinking milk, your baby will definitely pee afterward. 

If that pee finds an almost full diaper, it will go straight through the clothes and onto your baby’s bed.

10. Switch Brands

Change Diaper Brand To Prevent Diaper Leaks At Night

Changing the brand is exactly what I needed to prevent diaper leaks at night. 

Did you know that diapers of the same size from different brands can fit differently?

I didn’t and was quite surprised to discover this. 

Babies are also different. Sometimes it has nothing to do with one brand being better than the other. 

I guess it’s the same as one pair of jeans fitting differently on two people who wear the same size. 

Switching from Huggies To Pampers was the solution to preventing diaper leaks with our first baby. 

If your baby’s diaper keeps leaking at night no matter what you try, maybe it is time to switch to another brand. 

11. Be Prepared, just incase

Sometimes a leak just happens even when you thought you did everything right.

Be prepared for such instances.

If your baby sleeps for a long time or they drank more milk (or water for babies older than 6 months) than usual, keep in mind that you might be faced with a diaper leak when the baby wakes up. 

Don’t despair. 

Keep clothes and sheets ready for such times and embrace this less-exciting part of parenting.

Saying Goodbye To Diaper Leaks At Night

Almost every mom will be faced with leaky diapers at some point in their little one’s life. 

Sometimes the diapers themselves are the culprit (as in our case) and you have to do some trial and error to find the perfect fit. 

Other times the leaking is caused by different factors such as liquid intake. 

No matter what causes leaks on your end, the tips in this article will help you prevent diaper leaks at night. 

Here is to more peaceful nights and less chaotic mornings!
