From the moment your baby is born, you'll likely be spending lots of time looking at every inch of their little bodies—from chubby cheeks to cute small feet. But what happens when you spot something that seems concerning, like a red rash between the fold of their neck? It can be alarming, but a baby neck rash is usually not a cause for concern.
Here are the causes and symptoms of baby neck rashes, as well as ways to prevent and treat this common babyhood ailment.
What Is a Neck Rash in Babies?
Simply put, rashes happen when the skin is irritated. And, a baby has lots of opportunities for irritated skin, from wearing diapers to eczema. But one of the most common are neck rashes—caused by a combination of moisture and friction. It might be uncomfortable, but neck rashes come with the territory thanks to sensitive skin and brand-new immune systems. There is usually no call for alarm.
The Most Common Skin Rashes in Children and Their Causes
Causes of a Baby Neck Rash
In general, rashes are common in newborns. That includes neck rashes, which are common in babies under 4 months old. Babies truly have little bobbleheads due to their developing neck muscles. This causes the neck to create folds of skin. As the neck folds rub together, they create heat and friction. Combined with a steady supply of moisture from breast milk, formula, or drool, it's the perfect recipe for irritated skin.
The rash usually comes and goes but won't fully be under control until your baby is sitting, directing all moisture away from the neck and downward instead.
When It's a Yeast Infection on Your Baby's Neck
A neck rash can become infected with a yeast called Candida. This fungus is normally found on our skin, but it can sometimes grow too much. This can lead to Candidiasis, a fungal infection caused by the overgrowth. Babies are more prone to yeast infections. That's likely because their immune systems are still developing and they don't have enough gut bacteria to prevent yeast overgrowth.
“Fungus loves to grow in a moist environment, such as the skin folds of the neck—where sweat, saliva, and milk like to collect,” says Daniel Ganjian, MD, a board-certified pediatrician at Providence Saint John's Health Center in Santa Monica, California. “It is also caused by skin sensitivity, such as eczema or irritation to soaps/shampoo/wipes.”
But there's no need to worry. Yeast infections on your baby's neck are treatable.
Symptoms of a Baby Neck Rash
Symptoms of a neck rash are easy to spot. And, most likely, your baby will be cranky. You may see red, raw, weepy skin in your baby's neck creases.
If your baby has a yeast infection, you will need to consult their provider on the next steps, but you may see the following signs:
Redness with raised edgesRedness and tiny bumpsMoist, pink patchesRough, scaly patches Swelling Skin discolorationSores in the skin folds
Baby Neck Rash Prevention and Treatment
Keeping the area clean is important. You can use a baby soap, which can also be moisturizing. Be sure to dry the area thoroughly, then you can try applying a barrier cream like Aquaphor or A+D ointment to protect the skin. It's always best to speak with your child's provider before applying any ointment.
“I have parents try plain Vaseline as some kids are allergic to Aquaphor due to lanolin in it. If that doesn't help, I have them bring the baby into the office so we can determine if it is fungal,” says Gina Posner, MD, a board-certified pediatrician at Memorial Care Orange Coast Medical Center in Fountain Valley, California.
If you suspect a yeast infection, call your child's health care provider. They will most likely prescribe a prescription anti-fungal cream. There are also over-the-counter anti-fungal creams, which should clear up the infection in a few days, but it's always a good idea to speak with your child's provider first.

When to Call Your Medical Provider
If the rash is confined to the neck, your baby is most likely fine. But if it starts migrating to other body parts that are not areas of high moisture or friction, your baby should be seen by their provider. If your baby has the rash together with a high fever, this is also cause for concern as it can be an infection.
