If you’ve ever dealt with diaper rash, you know how heartbreaking it can be. One minute, your baby’s bottom is soft and smooth, and the next, it’s red, irritated, and causing them serious discomfort.
The worst part?
Every diaper change becomes a battle, with tears (from both of you!) as you try to soothe their sensitive skin. As a mom, all you want is to make it better—fast.
The good news?
Diaper rash is totally common, and with the right approach, you can soothe your baby’s skin quickly and prevent future flare-ups. The key is using gentle, effective, and natural products that won’t make things worse.
In this post, we’ll break down everything you need to know about how to heal your baby’s diaper rash fast—including what causes it, how to treat it, and our best mom-approved tips to keep that tiny tush happy and rash-free for good!
What causes diaper rash?
Diaper rash can seem to appear out of nowhere, but there are actually several common culprits behind that red, irritated skin. Understanding what’s causing your baby’s discomfort is the first step in healing it quickly and preventing future flare-ups. Here are some of the most common causes of diaper rash:
1. Prolonged exposure to wetness
Even the most absorbent diaper can only do so much.
When your baby’s skin sits in a wet or soiled diaper for too long, it creates the perfect environment for irritation. Urine contains ammonia, which can be harsh on delicate skin, while poop is full of bacteria that can cause further inflammation. That’s why frequent diaper changes are one of the best ways to prevent rashes before they start.
2. Friction and chafing
Tight diapers and too much movement can lead to rubbing, which weakens the skin barrier and makes it more prone to irritation.
If you notice red marks where the diaper edges sit, it may be time to size up or look for a more breathable option. Soft, well-fitting diapers will reduce unnecessary friction and keep your baby’s skin comfortable.
3. Harsh wipes and soaps
Many mainstream baby wipes and soaps contain fragrances, alcohol, and preservatives that can be too harsh for your little one’s sensitive skin.
These ingredients strip away the natural protective barrier, leaving the skin exposed and vulnerable. Instead of traditional wipes, opt for a gentle cleansing alternative like La Petite Creme's organic diaper lotion, which cleans, protects, and soothes all at once—without any harsh chemicals.
4. Yeast or bacterial infections
Diaper rash isn’t always just an irritation—it can sometimes be a yeast or bacterial infection.
Yeast thrives in warm, damp environments (like a diaper!), which is why rashes that don’t improve within a few days might need extra care. Yeast rashes often appear as bright red patches with raised edges and won’t respond to regular diaper creams.
Instead, look for natural ingredients with antifungal and antibacterial properties, like the limestone in La Petite Creme’s diaper lotion.
5. Sensitivity to diapers or detergents
Some babies have extra-sensitive skin and may react to the materials in their diapers, wipes, or even laundry detergent.
If you suspect this might be the case, consider switching to fragrance-free, hypoallergenic products and using a simple, non-toxic diapering routine to minimize irritation.
6. Introduction of new foods
If your baby has recently started solids, you might notice an increase in diaper rashes.
Certain foods, especially acidic ones like tomatoes, citrus fruits, and berries, can make their way through your baby’s system and cause irritation on the way out. If you suspect a food sensitivity, try keeping a food diary to track any patterns.
7. Teething and other developmental changes
Believe it or not, teething can contribute to diaper rash!
Many parents notice that their baby’s saliva increases when they’re teething, which can lead to looser stools (and more frequent diaper changes). Since poop contains natural enzymes that break down the skin, this can increase the likelihood of rashes.
Staying on top of diaper changes and using a protective barrier, like La Petite Creme’s diaper balm, can help keep irritation at bay.
By identifying and addressing the root cause of your baby’s diaper rash, you’ll be able to heal their skin faster and prevent future breakouts. Now, let’s talk about what you can do to get rid of that rash as quickly as possible!
Step-by-step: How to heal your baby’s diaper rash fast
Seeing your baby uncomfortable from a diaper rash is never fun, and you probably want to fix it as quickly as possible.
The good news is that with a few simple steps, you can help their skin heal and keep rashes from coming back. Here's what to do.
1. Give baby’s skin some air
One of the fastest ways to help heal diaper rash is to give that tiny bum some breathing room! Diaper rash thrives in warm, moist conditions, so letting your baby go diaper-free for short periods throughout the day can speed up the healing process. Try laying them on a towel or waterproof mat and letting them enjoy some fresh air.
2. Switch to a gentle, moisturizing cleanser
If you’re using regular baby wipes, now’s the time to swap them out.
Many conventional wipes contain alcohol and fragrances that can dry out and irritate your baby’s already-sensitive skin.
Instead, try La Petite Creme’s organic diaper lotion—a gentle, French-inspired alternative that cleans, nourishes, and protects in one step. Simply apply it with a cotton pad, and you’re good to go!
3. Apply a natural protective barrier
After cleaning your baby’s skin, you need to create a protective barrier to lock in moisture and keep irritants out.
But not all diaper creams are created equal! Many traditional diaper creams contain petroleum-based ingredients that can trap bacteria against the skin. Instead, opt for a breathable, lightweight balm like La Petite Creme’s Diaper Balm, made with organic olive oil, beeswax, and limestone water to soothe and protect.
4. Change diapers frequently
It sounds simple, but keeping your baby’s bottom as dry as possible is key.
Make sure you’re changing diapers every 2-3 hours, or immediately after a poop. If you’re using disposable diapers, consider trying a different brand—some babies react to certain materials.
5. Keep an eye on diet
If your baby has started solids, take note of any new foods that might be making diaper rash worse.
Acidic foods like citrus, tomatoes, and even certain fruits can cause irritation. If you suspect a food sensitivity, try eliminating it for a few days and see if the rash improves.
6. Use a natural remedy for extra healing
For stubborn rashes, a little extra TLC can go a long way.
Some moms swear by:
-
Breast milk – Packed with antibodies and healing properties, a few drops can help soothe irritation.
-
Oatmeal baths – Adding finely ground oatmeal to a warm bath can calm inflamed skin.

When to call your pediatrician
Most diaper rashes clear up within a few days with proper care, but in some cases, you might need a doctor’s help.
Call your pediatrician if:
-
The rash isn’t improving after 3-4 days of home treatment

You notice blisters, open sores, or pus
-
Your baby seems especially uncomfortable or in pain
-
The rash is spreading beyond the diaper area
If something seems off, trust your gut and check in with your pediatrician!
