When you become a parent, you will experience a severe learning curve and need to learn many things along the way. Whether you have a newborn or one on the way, learning what you can now will help save you time later. One of these things is how to change a diaper.
Before having kids, I had never changed a diaper because I was the youngest in my family and never really babysat. I had to learn how to change a baby’s diaper after we got home while recovering after a tough delivery with my first because my husband did all the diaper changes while we were in the hospital. So trust me when I say that being prepared will help as you embark on this journey of dirty diapers—whether you use disposal or go the cloth diapering route.
So if you have a toddler in your home and just need a refresher, or you’re a new mama wondering how to change a newborn diaper, we have you covered with baby diaper instructions below.

How to change a newborn diaper: What you’ll need
1. Diapers of two sizes
While you should have a few newborn-sized diapers, you should also make sure that you have size 1. Your newborn baby will grow fast, so having a size up and ready to go will be invaluable. This change can happen quicker than you realize, and you don’t want to run out of diapers. So whatever style or brand you decide on—natural diapers, a diaper subscription service, or good old Pampers—you’re going to need more than you think you do.
2. Wipes
Wipes are another item you want to be sure not to run out of, and, like all these items, they need to be within reach. There are many options, and not all of them will work for your baby. It is a good idea to start with those for sensitive skin, and then go from there. (Check out our picks for the best eco-friendly and natural baby wipes).
3. Changing pad
You need something soft to change your baby on. This could be a changing pad, blanket, or even a towel. As long as you put it on something safe like a changing table or the floor, you can use whatever soft item you like. Just keep in mind that it may get dirty.
4. Diaper pail or garbage can
You need somewhere to dispose of the diaper. You could use a fancy diaper pail or a garbage can. It is really up to you. If you decide on cloth diapers, you will need a wet bag to put them in until you wash them.
5. Diaper cream
When they’re tiny, you’ll change your baby often, so be sure to have diaper cream on hand. They will probably get a rash, and you will want to be able to soothe it quickly.
6. A safe place to change your baby
You could use a changing table, a dresser with a contoured changing pad, a bed or the floor. For those early days, it will be helpful to have a place up higher to change your baby. Once they get bigger and start moving around more, you can pretty much change them anywhere that’s safe.
7. Hand sanitizer
Sanitizer may be a good thing to keep in your changing area since you will need to move your baby before you can wash your hands.
The process: How to change a diaper
Step 1: Taking off the old diaper
Before you get started, make sure you have all items within reach. Lay your baby down and unfasten the onesie. Slide it up to try to keep it out of the way of any accidents. Put the clean diaper under the dirty one to have it ready. This practice will save you time and help keep the changing area clean.
Step 2: Cleaning
Unfasten the dirty diaper, fold it and push it closed under your baby’s butt. This practice will get some of the dirty stuff out of the way. Then, clean between all the folds with a wipe.
Step 3: Apply diaper rash cream as needed
If (when) your baby develops a diaper rash, be sure to apply cream each time until it heals. The cream isn’t necessary if there’s no rash present, but it is helpful when there is one.
Step 4: Close it up and stick it
Fully close the diaper, wrap it and stick the tabs to it. This will help everything stay inside when you throw it away. Fasten the tabs on the clean diaper and close up the onesie.
Step 5: Sanitize or wash
If you have hand sanitizer, use it now. If you want to wash your hands, place your baby in a nearby crib or bassinet.
Step 6: Hugs!
Don’t forget the after-changing cuddles!
Tips and tricks to changing a diaper
How to change a newborn diaper
When you have a newborn, they will go through diapers often. It’s usually about 10 diapers daily, so be sure you’re changing them often enough. The color of poop will also change from green to more yellow-green. Some red is also common in the first few days but still contact your doctor.
When changing a newborn, you must also be careful of the umbilical cord stump. Be sure to fold the diaper down a bit, so it’s not on top of this stump. If you’re using newborn diapers, these are usually cut to accommodate the stump, but your baby may need to go up in size before the stump falls off.
Diaper changing tips for girls
For girls, make sure you’re wiping front to back to avoid infections. You should also clean between the folds of the skin gently.
Diaper changing tips for boys
Many moms have a problem getting peed on by boys, so cover the penis with another diaper or cloth to keep pee from flying in the air. When you close the diaper, the penis should be pointing down, which can also help prevent leaks.
Diaper changing tips for toddlers
Once you’re out of the newborn stage, you will need to deal with a wiggly toddler. You can entertain them with a song, talk or give them a toy while changing their diapers. You can also have them help by collecting supplies for you. If you are changing a diaper with just pee, some parents rely on changing the diaper while their toddler is standing up.
There’s so much stuff to learn as a new parent, but you can prepare well for diaper changes ahead of time. Knowing how to put a diaper on a baby is a key parenting skill. The steps above will help you understand how before you bring your baby home.
