As parents, we want nothing more than for our little ones to be happy and comfortable. That’s why a red, irritated bum area can feel so stressful—especially if your baby is crying during diaper changes or waking more often from discomfort.
The good news? Diaper rash is extremely common (and treatable!)—most babies experience it at some point in their first few years. At Northwest Family Clinics, we’re here to help you understand what’s causing your baby’s diaper rash, how to treat it, and most importantly, how to help prevent it from happening again.
What Causes Diaper Rash?
Diaper rash—also known as diaper dermatitis—is a form of inflamed skin that appears as redness, bumps, or peeling skin in the diaper area. It can be caused by several things, often in combination. Some of the most common causes include:
Prolonged exposure to moisture or stool
Diapers that stay wet too long can irritate your baby’s sensitive skin. Stool, especially when your baby has frequent bowel movements, can be especially harsh due to digestive enzymes that break down Baby’s sensitive skin.
Friction and chafing
A snug diaper that rubs against the skin can break down your baby’s natural barrier, making rashes more likely.
Irritants from wipes, soaps, or diapers
Some babies are sensitive to fragrances or alcohol in baby wipes, soaps, or even certain diaper brands.
Yeast infections
A bright red rash that spreads into the skin folds and doesn’t improve with regular diaper cream may be a yeast (fungal) infection. These often happen after antibiotic use or when a regular rash gets worse instead of better.
New foods or teething
Introducing solids can change the acidity of your baby’s stool. Even teething can cause looser stools, both of which can increase the risk of rash.

How Can I Treat Diaper Rash at Home?
First, take a deep breath. Diaper rash is treatable, and most mild cases respond well to at-home care. Here are some of our top recommendations:
1. Keep the area clean and dry
Change your baby’s diaper frequently, ideally as soon as it's soiled. Gently clean the area with water and a soft cloth or fragrance-free, alcohol-free wipes.
2. Give your baby diaper-free time
Let your baby’s skin breathe by giving them time without a diaper. Even 10-15 minutes a few times a day can make a difference. If you don’t have time for this, you can pat dry the area with a dry tissue or cloth.
3. Use a protective barrier cream
Look for a thick ointment (like Aquafor) or diaper cream (often containing zinc oxide). Apply a generous layer to dry skin with each diaper change. These products help create a barrier to moisture and protect irritated skin. If this process is done consistently, it will only take a few days for the rash to improve.
4. Choose gentle products
Avoid wipes or lotions with alcohol, fragrance, or harsh chemicals. Opt for hypoallergenic, unscented options—and consider switching diaper brands if irritation persists. Learn more about taking care of your baby’s sensitive skin here.
5. Watch for yeast infections
If the rash appears red and shiny, spreads into the skin folds, or doesn’t improve in 2–3 days with over-the-counter treatments, it might be a yeast infection. In this case, your provider can recommend or prescribe an antifungal cream.
When Should I Call My Doctor?
Most diaper rashes clear up within a few days of at-home care. However, you should schedule an appointment if:
- The rash doesn’t improve after 3 days
- It’s spreading quickly or appears bright red and raw
- Your baby has a fever or seems unusually fussy
- There are signs of blisters, open sores, or pus
Remember, we’re always here to help—whether it’s a stubborn rash, a question about products, or simply reassurance that you’re doing the right thing (because you are!).
How Can I Prevent Diaper Rash in the First Place?
Preventing diaper rash isn’t always possible, but these habits can help keep your baby’s skin healthy and irritation-free:
- Change diapers frequently, especially after bowel movements
- Clean gently and pat dry—avoid rubbing
- Apply a barrier cream at the first sign of redness
- Use diapers that fit well but aren’t too snug
- Try diaper-free time daily
- Avoid products with fragrance or alcohol
Remember, Diaper Rash is Common, Treatable and Preventable
Diaper rash is part of the parenting journey, and it doesn’t mean you’re doing anything wrong. Babies have sensitive skin, and even the most careful parents will run into diaper rash now and then. The key is early treatment, lots of TLC, and support from a healthcare team who knows and cares about your family.
If you have questions or concerns, don’t hesitate to reach out to your provider at Northwest Family Clinics. We’re here for your baby’s first rash, their first steps, and every milestone in between.
