Do Diapers Expire? Is It Safe to Use Old Ones? Things You Need to Know!

Did you happen to find an outstanding sale on diapers at your local grocery store that you find never happens that you are fully committed to taking advantage of?

Trust me, I’ve been there and done that more times than I could count. And if there’s anything that I’ve learned after having children, babies’ poop is a lot.

You may be reading this and thinking how out of left field of a question “do diapers expire?” maybe. And you are totally right!

However, this is an actual question I had when I had my first child. After doing my research, I think it’s definitely a question that many new parents have! So, let’s take a look, shall we?

What Are Diapers Made Of?

Before answering your burning question “do diapers expire?” Let’s take a look at what diapers are made of first, so we know if there’s any part of the diaper that could go bad as opposed to others because if you really take a look at diapers, you’ll notice that there are a lot of parts to those suckers!

1. Adhesive Fastener tabs

Let’s start with the diaper’s most prominent part, the little adhesive tabs on the diaper’s waistband. 

The tables are typically made out of plastic of spandex material that allows for some stretch.

These tabs allow you to fasten the diaper around your child to ensure that it is snug and won’t fall off when they move. 

This has happened to me once before, and all I can say is that it was not pretty.

2. Elastic Sides

All diapers have a spandex material at the leg holes. The spandex allows for a comfortable fit around the baby’s upper thigh and makes sure that there is no leakage along the legs’ sides.

3. The Outermost Layer

The diaper’s outermost layer is made up of a mix of paper and plastic fibers that are ultra-soft and comfortable for your baby’s skin. 

This layer not only stops leaks from happening but also allows airflow into the diaper so your baby’s bottom can breathe. How adorable!

4. The Innermost Layer

This is where all the magic happens, ladies and gentlemen. The core of the diaper is made of sodium polyacrylate. 

Try saying that 10 times fast! Sodium polyacrylate is what we call a polymer, which is super absorbent and resistant to liquids and poop!

Okay, So Can Diapers Actually Expire?

Now that we have that out of the way, it’s time to answer your burning question. And the answer is, no, diapers cannot expire! 

Now you can go to your closest grocery store and pile up for weeks if you want to, and they are the perfect gift to give to your friends or family who is expecting a little one! 

However, although disposable diapers do not have an expiration date, it is recommended that you use them within two years when you actually purchase the diaper, so keep this in mind before you go totally crazy with your purchases. 

Manufacturers suggest using the diaper within the first two years because the diaper itself can become discolored.

The fragrance could change and go stale, and there is a chance that the diaper’s performance might not work as well as before. 

And you know what that means? Poop everywhere. I’m shivering just thinking about it. 

No, thank you! If you do end up using older diapers, just check your baby a little more often to make sure that there are no leaks throughout the day!

What Is the Best Way to Store Your Diapers?

Okay, now that we know that there is no expiration date for disposable diapers, here are a few tips and tricks that I suggest for you to keep your diapers fresh for as long as possible!

1. Keep Them in a Dry and Cool Place

I definitely recommend that you keep your diapers unopened and away from direct sunlight, as it could cause the glue and plastic to become deformed. My favorite place is to put them in a well-ventilated closet or on extra shelving you may have.

2. Make Sure the Diapers Are in Their Original Packaging

I know it’s tempting to try and make extra space in your storage by taking the diapers out of the plastic and the cardboard box they originally came in.

However, I suggest keeping the diapers in the original seal. It further protects the diaper from any moisture damage that may be in the air.

3. Create Your Own Vacuum Seal

If you already have a box of opened diapers and, after reading this, you have the urge to try and re-seal the original packaging, I am here to tell you that yes, this is totally possible! 

You will want to grab your diapers and wrap them in a thin layer of plastic as securely as you can. 

Next, squeeze out as much air as possible and seal the plastic with tape. You can also use your vacuum to suck out all the air in the actual plastic for an extra tight seal as well.

What Are My Final Thoughts?

Yay, we’ve made it to the end!  While diapers don’t have an actual expiration date,  they tend to lose some of their overall effectiveness as time passes. 

However, that doesn’t mean you have to throw all your diapers out and start fresh!

Like I said before, a lot of the changes that occur to the diaper over time

have to do with its cosmetic appearance as well as its effectiveness when it comes to absorption.

Remember to be on a careful lookout for any leaks or poop, and you should have no issues with them! Remember to also keep the stored correctly for the perfect results!

Now that we’ve made it to the end, I want to know your thoughts on using older diapers? How long have you stored diapers in the past? 

And what was your experience in using them after their recommended expiration date?
