Why does my baby keep peeing through his diaper?
If you’re like me, you probably ask this question on a very regular basis. I figured if I could discover what was causing these bedwetting problems, I could finally find the solution to overnight diaper leaking.
Here are four of the most likely reasons why babies regularly pee through their diaper overnight:
1 – Your baby’s body doesn’t make enough Antidiuretic Hormone.
Antidiuretic hormone (ADH) is the hormone in our bodies that tells us to decrease urine production.
In adults, ADH levels are increased overnight so you’re not constantly running to the bathroom all night long.
But generally baby’s ADH levels are lower and urine production stays high all night long. If your baby has lower ADH levels and a particularly full bladder, he’s much more likely to leak through his diaper before morning.
2 – Your baby is in between diaper sizes.
When your baby is between sizes, neither the smaller or bigger size fits juuuust right. Until she’s fully grown into her new size, you’re more likely to see overnight diaper leaking for a while.
3 – Your baby moves around a lot.
If your little one moves around a lot overnight, her diaper is constantly shifting and rearranging. Since the diaper isn’t staying snug in one spot, this increases the chances of overnight diaper leaking for your baby.
4 – Your baby sleeps on his stomach.
Stomach sleeping also increases the odds of leaking through diapers overnight.
Stomach sleeping seems to put pressure in different places on your baby’s diaper and increases the odds of your baby peeing through their diaper.
How to Stop Baby from Peeing Through Diaper Overnight:
Okay, you know a few of the most reasons WHY your baby is peeing through her diaper overnight, and hopefully feel relieved that she really isn’t on a mission to destroy your morning routine with extra loads of laundry and emergency baths before daycare.
So let’s dive into 13 of the top secrets for stopping overnight diaper leaking once and for all.
1 – Change your baby’s diaper right before bed:
2 – Use overnight diapers:
Overnight diapers are specifically designed with ultra-absorbent layers to keep your baby dry for 12+ hours.
They usually cost a little more than regular diapers because they are more absorbent, but are definitely worth it for anyone struggling with leaking through diapers overnight.
We typically see a LOT more problems when we forget to stock up on our favorite overnight diapers before bedtime.
3 – Use a larger diaper at night:
Overnight diaper leaks happen when your baby is peeing too much for their diaper to absorb. So if your baby is suddenly leaking through diapers a lot more, try going up a size overnight.
This helps to give more space (and more absorption) for your baby overnight.
4 – Change diaper brands:
Every brand fits your baby and absorbs urine a little differently.
If your baby is regularly peeing through pajamas overnight, try out a few different brands. And remember, just because one brand has been working doesn’t mean it will always work, so experiment a little to find what’s right for your baby right NOW.
5 – Use cloth diapers:
Cloth diapers are known for being more absorbent than disposable diapers, so switching to cloth diapers overnight can be super helpful for stopping your baby from peeing through his diaper every night.
6 – Add a diaper liner across the top of the diaper:
Again, when your baby is leaking through her diaper, it’s because she has too much urine for the diaper to absorb.
An easy way to fix this is to add a diaper liner across the top of the diaper.
Pay attention to whether your baby is always leaking through the front or the back and then add the diaper liner on whichever side is always wet in the morning.
7 – Line your baby’s diaper with a pad:
Another creative way to stop your baby from peeing through his diaper at night is to add a pad to his diaper before bedtime.
This gives another super absorbent to your baby’s diaper. Once it leaks through the pad, it will go to the mostly-dry diaper and decrease the odds of peeing through the diaper and soaking your baby’s pajamas and bed sheets.
8 – Use Peejamas:
Although they are technically designed to help toddlers master overnight potty training, they have been our absolute favorite tool for stopping overnight diaper leaks and the only thing we’ve tried that have really worked.
After we put on our baby’s overnight diapers, we put on a pair of our Peejamas. When he goes to the bathroom overnight, anything that leaks through the diaper is soaked up by the built-in cloth diaper and his pajamas and bed sheets finally stay wet all night long.
9 – Point boy parts downward:
This is an important step that lots of parents forget.
If your baby boy is peeing through his diaper at night, always make sure to point his boy parts down before strapping up his diaper. This makes sure that he is peeing toward when he goes to the bathroom instead of sending everything up over the top of his diaper.
10 – Adjust the diaper:
Adjusting your diaper a little can also help to prevent overnight diaper leaking.
For bedtime diapers, we always make sure to pull the diaper forward just a little so it sits higher on our baby’s stomach. This helps absorb more in the front, since that’s where our diaper leaks usually happen.
We also adjust our straps slightly. Instead of taping it directly across his hips, we tape it at a slightly upward angle to put more pressure on these areas and help absorb more liquid if he has a full bladder overnight.
Also, take a few seconds to make sure that the fabric by your baby’s legs is pulled out and nothing is bunched up. This area typically gets a little folded during diaper changes, but straightening everything out helps your diaper to be as absorbent as possible and is especially helpful if your baby keeps peeing through the side of the diaper.
11 – Change diapers during overnight feedings or wakings:
It’s generally safe for your baby to sleep with a wet diaper without worrying about a diaper rash (although if your baby already has a rash or is prone to rashes, ask your doctor if you should wake up your baby when she is wet).
However, if you struggle with diaper leaking, I highly recommend that you check your baby’s diaper and change it anytime your baby wakes up for a feeding or is fussing overnight.
This gives you a fresh diaper to make it through the rest of the night and will help your baby to fall asleep faster since a dry diaper is much more comfortable than a wet one.
12 – Encourage back sleeping:
Babies that prefer belly sleeping are much more likely to leak through their diapers than back sleepers.
All of that extra pressure on the front of their diaper seems to lead to more problems with peeing through their diapers.
As much as you can, encourage your baby to sleep on her back. This is generally a safer sleep habit and will help decrease extra laundry and baths after a wet morning.
Always put your baby down for bedtime and naps on her back. If she wakes up overnight, put her back to sleep on her back to encourage back sleeping as much as you can.
13 – Limit certain liquids at night:
I’m not a big fan of limiting liquids, so I offer this tip with caution. If your baby is nursing or taking a bottle or asking for water, I think you should give it to your child.
Being thirsty is just going to make your baby feel miserable and sleep worse, and could lead to dehydration.
However, you can certainly limit certain types of liquids at bedtime, especially when you’re struggling with super wet overnight diapers.
Limit sugary drinks in the evenings (or all the time since your baby doesn’t need juice or sugary drinks) since these extra beverages might increase overnight bed wetting.
What can you do if your baby is constantly leaking through diapers at night?
While you test out these different options to see what’s best for your baby, here are a few ideas to make it less of a pain the next time your baby pees through her diaper.
Add a blanket or mattress pad under your baby.
This gives an extra layer between your baby and the bed. When your baby leaks through her diaper and pajamas overnight, you can change pjs and switch out the extra blanket without having to wash all of the sheets too.
Note: If your baby is less than 12 months old, it is not recommended that your baby sleep with anything extra in the bed. If using an extra blanket, make sure that it is tight fitting and your baby can’t pull it up and wrap it around her head.
Layer your baby’s mattress.
If you have an extra baby’s mattress, double up to save some time on overnight changings.
Mattress. Sheets. Mattress. Sheets. Baby.
If your baby leaks through pajamas overnight, you can take off the extra mattress and already have a clean layer underneath for the rest of the night.
Skip bed sheets or pajamas for a while.
If you live in a warm climate and know that your baby won’t be too cold overnight, you can have your baby sleep without pajamas to make overnight diaper changes easier, plus limit extra laundry if your baby soaks through her diaper.
You can also try to go without bed sheets for a little while and then just wipe off your baby’s mattress during overnight diaper changes and in the mornings as needed.
Change your baby when YOU go to bed.
If your baby is regularly peeing through everything overnight and doesn’t usually wake up for a diaper change, you can do an extra diaper change when you go to bed.
We never did this, because our baby is NOT happy when we wake him up, but this has worked really well for other babies I’ve worked with who stay fairly sleepy during this extra diaper change and then drift right back to bed.
Invest in a washable mattress.
Mattresses can get pretty gross if your baby is constantly peeing through them night after night.
I highly recommend checking out these mattresses, which are 100% machine washable and might be the coolest things since sliced bread.
