Baby Rash Behind Ears
The short answer
Rashes behind the ears are very common in babies and are usually caused by moisture buildup, seborrheic dermatitis (cradle cap), or eczema. Keeping the area clean and dry, and applying a gentle moisturizer, usually resolves it quickly.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
In newborns, rashes behind the ears are most often seborrheic dermatitis, the same condition that causes cradle cap on the scalp. It appears as yellowish, greasy, scaly patches. Milk and drool can also collect behind the ears during feeds and cause irritation. Gently cleaning the area during baths and patting it dry is usually all that is needed.
At this age, drool and spit-up commonly pool behind the ears, especially when babies lie on their sides. This moisture can lead to redness and even cracking of the skin. Eczema may also first appear in this area. Keeping the skin dry and applying a fragrance-free moisturizer or thin layer of petroleum jelly helps protect the skin.
As babies become more active and sweat more, the warm, enclosed area behind the ears can stay moist and become irritated. Eczema behind the ears may become more persistent at this stage. If the rash is itchy and your baby scratches it, watch for signs of secondary infection such as oozing or crusting.
Toddlers may develop rashes behind the ears from eczema, sweat, or contact dermatitis from shampoos and soaps. Seborrheic dermatitis can persist or recur in this age group. If the area becomes consistently cracked and weepy, or if your child seems bothered by pain or itching, discuss treatment options with your pediatrician.
What Should You Do?
When to take action
- Mild redness behind the ears that improves with gentle cleaning and drying
- Yellowish, greasy scales similar to cradle cap on the scalp
- Slight dry patches that respond well to moisturizer
- The rash is persistent, worsening, or spreading despite good skin care
- Skin behind the ears is cracking deeply or weeping fluid
- Your baby seems uncomfortable or is scratching at the area frequently
- The area becomes very swollen, warm, red, or shows signs of infection such as pus or honey-colored crusting
- Your baby develops a fever along with a worsening rash behind the ears

Related Skin Concerns
Baby Eczema (Atopic Dermatitis)
Baby eczema is extremely common, affecting up to 20% of infants, and is not caused by anything you did wrong. It shows up as dry, red, itchy patches and is very manageable with consistent moisturizing and gentle skin care. Most children outgrow it by school age.
Cradle Cap (Seborrheic Dermatitis)
Cradle cap is a very common, harmless condition that causes yellowish, greasy, scaly patches on your baby's scalp. It is not caused by poor hygiene, it does not bother your baby, and it almost always clears up on its own within the first several months of life.
Baby Rash in Skin Folds - Neck, Armpits, and Creases
Rashes in baby's skin folds (neck, armpits, groin, behind ears, elbow and knee creases) are extremely common because these warm, moist areas trap moisture from drool, spit-up, sweat, and milk. The medical term is intertrigo. Most fold rashes respond to keeping the area clean and dry. If the rash is bright red, has satellite spots, or has a yeasty smell, it may have developed a yeast (candida) infection and need antifungal treatment. Keeping folds dry is both the treatment and prevention.
Baby Acne vs Eczema: How to Tell the Difference
Baby acne and eczema can both cause facial rashes, but they look and feel different. Baby acne appears as small red or white bumps, similar to teenage acne, usually on the cheeks, nose, and forehead. Eczema causes dry, rough, red, itchy patches. Baby acne resolves on its own by 3 to 4 months, while eczema may need ongoing management.
Baby Acne (Neonatal Acne)
Baby acne is a very common, harmless condition that appears as small red or white bumps on your newborn's face, usually around 2-4 weeks of age. It is caused by maternal hormones still circulating in your baby's system and clears up on its own within a few weeks to months without any treatment.
Alopecia Areata in Babies
Alopecia areata is an autoimmune condition where the immune system attacks hair follicles, causing round, smooth patches of hair loss. While uncommon in babies, it can occur at any age. The condition is not painful or contagious. Many children experience spontaneous hair regrowth, though it may take months. Your pediatrician or dermatologist can confirm the diagnosis.
