Here is the ULTIMATE step-by-step guide on how to change a baby’s diaper.

No more worrying on where to begin or what to use when doing a diaper change.

We got you covered!

Here are the 7 steps to change a diaper.

It’s EASY, fast, and will help keep your babe safe from infection while protecting their ever so sensitive skin. 🙂

Plus, we will cover the most frequently asked questions at the end of this post so be sure to stick around!

Let’s get started.

The Basics: Do This FIRST

Make sure you are changing your little one’s diaper AT LEAST every 2 to 3 hours. Steps-to-Change-a-Diaper


Your little one is prone to having a blowout around 3 to 5 times a day and will usually urinate every 1 to 3 hours.

Sleeptime diaper changing is a different scenario which we will tackle in a hot minute below.

AND make sure you have the right size diaper on your kiddo.

How can you tell?

If your baby has red marks on their thighs, tummy, OR if you notice the fastening tapes do not reach the center of their waistband…that is a RED FLAG.

Eek their diaper is too small!

It’s time to move UP a size.

On the flip side, if the fastening tapes overlap at the waistband then it is too big…move down a size. 🙂

Pediatric Dr. Brandon Smith shares, “There are two measurements parents and caregivers can use when trying to make heads or tails of baby diaper sizes: the size on the box and the size of the baby. Each diaper brand may have slightly different sizing than other brands, so it’s important to always refer to the size chart on the package you’re using to ensure proper fit.”

Now that we have the basics down, let’s explore step-by-step how to change a baby’s diaper.

Step 1: Prepare the diaper changing table with the RIGHT supplies.

Items you will need readily at your fingertips:

  1. Glovesprepare-the-diaper-changing-table-with-the-right-supplies
  2. Clean diaper
  3. Diaper cream
  4. Wipes
  5. Disposable diaper bags
  6. Sanitizing wipes
  7. Disposable liner
  8. Clean clothes

Note: Please keep in mind the items on this list are optional.  For instance, if you did not want to get disposable wipes, you can use a wash cloth to clean your little one with warm water and baby soap. 

To start, put on gloves to wear.

This helps keep the poo off you or a little tinkle shooting your way.

When you have the gloves on, you can also quickly cover your kiddo if they start doing their business right then and there which helps you prevent a possible mess.

BUT if this does happen, you may want to change those gloves again. 🙂

Make sure your changing table is wiped down and sanitized, then cover it with a disposable liner.

The disposable liner is a hassle free way to clean up the mess quickly because you can toss it in the trash right after the diaper change.

Plus, having a disposable liner ensures your babe is being changed on a clean surface at ALL times to avoid infection or contamination.

Have two disposable bags on hand for each diaper change.


One is to dispose of your dirty diaper in and the other is for clothes that may become soiled.

Be sure to keep those clean clothes handy!

Step 2: Remove the dirty diaper and clean the area well.

Now that your changing area is equipped with what you need, place your kiddo on your changing table.

Unfasten the old diaper.

Clean the diaper area on your kiddo using gentle disposable wipes.

Make sure to wipe from the front to the back if you are changing a girl.

Reason being, it will help to prevent bacteria transferring from your baby’s bottom to their vagina or urethra, and causing an infection.

Put the dirty diaper and soiled clothing (if this applies to you) each in separate disposable bags.

You can clean the soiled clothes and dry them later on.


Step 3: Remove the trash carefully.

Changing a baby’s diaper equates to a big pile of trash!

It’s icky but true.

You will have many messy diapers and wipes to discard throughout the day.

The key is to have a decent trash can and trash bags to keep those dingy smells trapped!

If you want to REALLY seal in the “stinkies”, I recommend using a scented biodegradable diaper bag to toss into your trash can.

Plus, you can put these in your diaper bag to take with you on the go.

Step 4: Replace the soiled diaper with a clean diaper.

Remove the dirty diaper and toss it into a disposable diaper bag.

Place a clean diaper underneath your babe’s bottom.

Apply a dime size amount of diaper cream directly onto your finger (your pointer or middle finger typically work best).replace-the-soiled-diaper-with-a-clean-diaper

Apply the most amount of cream on your baby’s bottom cheeks or any areas that may look red and inflamed or irritated.

Wipe off your fingers with a tissue.

Fasten your baby’s clean diaper so it fits perfectly snug.

You don’t want it too loose as it can easily fall off when your little one is moving around.

AND you don’t want it too tight. Check by putting two of your fingers at the tummy waistline area. If two fingers can not fit, then the diaper is most likely too tight.

Then be sure to wash your hands.

Step 5: Clean your baby’s hands.

While you’re changing your little one’s diaper, they may touch things that make their hands dirty.

Try your best to keep your baby’s hands clean with clean water and a safe gentle hand washing soap.

OR you can use safe hand sanitizing wipes (which you can toss into your diaper bag when out and about).

Step 6: Clean the entire surface after changing your babe.

The surface where your diaper changing went down should be left squeaky clean.

Take time to clean the entire surface to keep your little one safe.

Toss the disposable changing liner into the trash and replace with a new one.

Simply wipe down the changing pad with sanitizing wipes or gentle detergents that will not irritate your little one’s skin.

Then clean the changing table surface and its surroundings.

Step 7: Clean your hands.

After you are done with your hassle free diaper change, clean your hands well. 🙂 Steps-to-Change-a-Diaper

I know this may sound self-explanatory but it ensures safety for both you and your little one.

Use soap and clean water to wash your hands, then rinse them thoroughly.

Use running water to clean off all dirt.

Ensure you maintain a high level of cleanness by keeping your hands clean because it reduces the chances of contaminating the surfaces and your babe.

Frequently Asked Questions

Should you change a diaper before or after feedings?

As long as your babe is comfy, happy, and mess free, it’s perfectly ok to NOT change their diaper before a feeding.

You can do it after if needed.

Should you change a poopy diaper when you baby is sleeping?

Yes, but not immediately.

If you are breastfeeding your little one, their poo will not be as harsh or irritating so you can hold off a little bit on changing.

BUT if your babe is on formula, then you may want to change their diaper sooner than later.

How long can you leave the diaper on overnight?

You can leave a diaper on for up to 12 hours.

Be sure to use an overnight diaper so it is extra absorbent which can hold up to 25% more than regular diapers.
