Baby skin is sensitive and changes frequently. If you are noticing is it ringworm or eczema, here is what you need to know.
The short answer
Ringworm and eczema can look similar, but ringworm typically forms a distinct ring shape with a clearing center and raised, scaly edges, while eczema tends to appear as irregular dry, red patches. Ringworm is a fungal infection (not actually a worm) that is treatable with antifungal cream, while eczema is a chronic condition managed with moisturizers and sometimes medicated creams.
Key takeaways
- Ringworm and eczema can look similar, but ringworm typically forms a distinct ring shape with a clearing center and raised, scaly edges, while eczema tends to appear as irregular dry, red patches. Ringworm is a fungal infection (not actually a worm) that is treatable with antifungal cream, while eczema is a chronic condition managed with moisturizers and sometimes medicated creams.
- Usually normal when: A single small, round, mildly scaly patch that is not spreading rapidly or causing significant discomfort
- Call your doctor if: The affected area is becoming very swollen, boggy, tender, or oozing pus, which may indicate a kerion (an inflamed fungal abscess on the scalp) or secondary bacterial infection
- Varies by age — see the age-by-age breakdown below
“Eczema is very common in babies and children. About 1 in 10 children will develop eczema, typically starting in the first few months of life.”
This is one of the most common questions parents ask. Searching for answers means you care.
What Parents Should Know
According to AAP, AAD, Mayo Clinic guidelines, ringworm and eczema can look similar, but ringworm typically forms a distinct ring shape with a clearing center and raised, scaly edges, while eczema tends to appear as irregular dry, red patches. Ringworm is a fungal infection (not actually a worm) that is treatable with antifungal cream, while eczema is a chronic condition managed with moisturizers and sometimes medicated creams. At 0-6 months, ringworm is uncommon in very young infants but can occur, especially if there is a pet in the home or an infected family member. At this age, round red patches are more likely to be a form of eczema, nummular dermatitis, or a contact reaction. If you notice a round, scaly patch with a clearing center that is expanding outward, have your pediatrician examine it. A simple skin scraping test can distinguish ringworm from eczema. It is generally considered normal when a single small, round, mildly scaly patch that is not spreading rapidly or causing significant discomfort. However, you should contact your pediatrician promptly if the affected area is becoming very swollen, boggy, tender, or oozing pus, which may indicate a kerion (an inflamed fungal abscess on the scalp) or secondary bacterial infection.
Normal vs. Concerning
By Age
What to expect by age
0-6 months
Ringworm is uncommon in very young infants but can occur, especially if there is a pet in the home or an infected family member. At this age, round red patches are more likely to be a form of eczema, nummular dermatitis, or a contact reaction. If you notice a round, scaly patch with a clearing center that is expanding outward, have your pediatrician examine it. A simple skin scraping test can distinguish ringworm from eczema.
6-12 months
As babies become more mobile and interact with the environment, their exposure to fungi increases. Ringworm on the body (tinea corporis) presents as one or more circular, red, scaly patches with raised borders and a clearer center. Eczema at this age usually appears in skin creases and is itchier and drier looking. A key difference is that ringworm patches tend to expand outward over days, while eczema patches stay in the same general areas.
1-2 years
Toddlers in daycare or who have pets are more commonly exposed to ringworm. It can appear on the scalp (tinea capitis), causing a scaly bald patch, or on the body. Scalp ringworm is especially common in toddlers and requires oral antifungal medication, not just cream. Eczema at this age tends to follow a chronic waxing and waning pattern in predictable locations like elbows and knees, whereas ringworm appears as a new isolated patch.
2-3 years
At this age, children can contract ringworm from playmates, shared surfaces, or animals. If your toddler develops a new ring-shaped lesion, avoid applying eczema creams containing steroids before getting a diagnosis, as steroid cream can make ringworm worse and harder to recognize (a condition called tinea incognito). Your pediatrician can often diagnose ringworm visually or with a simple skin culture.
What to Tell Your Pediatrician
- Describe when you first noticed is it ringworm or eczema and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if a circular rash is expanding, not improving with moisturizer, or you are unsure whether it is ringworm or eczema.
- Mention if your child has a scaly, bald patch on the scalp, which may be scalp ringworm requiring oral treatment.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- A single small, round, mildly scaly patch that is not spreading rapidly or causing significant discomfort
- Dry patches in typical eczema locations (cheeks, elbows, knees) that improve with moisturizer
- A ring-shaped patch that responds to over-the-counter antifungal cream within 1-2 weeks
- A circular rash is expanding, not improving with moisturizer, or you are unsure whether it is ringworm or eczema
- Your child has a scaly, bald patch on the scalp, which may be scalp ringworm requiring oral treatment
- The rash has been present for more than 2 weeks without improvement despite treatment
- The affected area is becoming very swollen, boggy, tender, or oozing pus, which may indicate a kerion (an inflamed fungal abscess on the scalp) or secondary bacterial infection
- Your child has a widespread rash with fever and seems unwell, which could indicate a more serious condition than either ringworm or eczema
What You Can Do at Home
- Keep track of when you notice is it ringworm or eczema — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that a single small, round, mildly scaly patch that is not spreading rapidly or causing significant discomfort — this is generally within the range of normal.
- At 0-6 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Use fragrance-free, hypoallergenic products on your baby's skin. Avoid over-bathing — 2-3 baths per week is usually sufficient.
- While monitoring at home, seek immediate care if the affected area is becoming very swollen, boggy, tender, or oozing pus, which may indicate a kerion (an inflamed fungal abscess on the scalp) or secondary bacterial infection.

Related Skin Concerns
My Baby Has an Extra Nipple (Accessory Nipple)
Accessory (supernumerary) nipples are one of the most common minor congenital findings, occurring in about 1 in 18 people. They appear as small, flat, often pigmented bumps along the "milk line" — an embryonic line running from the armpit to the groin on each side. Most people mistake them for moles. Accessory nipples are almost always harmless and require no treatment. In rare cases, they may be associated with kidney abnormalities, so some pediatricians recommend a renal ultrasound if one is found, though this practice varies.
My Baby Was Born with a Raw Spot on Their Scalp (Aplasia Cutis)
Aplasia cutis congenita (ACC) is a condition where a baby is born with a small area of missing skin, most commonly on the scalp. It occurs in about 1 in 10,000 births. The affected area may look like a raw wound, an ulcer, or may have already healed into a thin, shiny scar by the time of birth. Most cases are small, isolated, and heal well with basic wound care — the area eventually forms a hairless scar. Larger defects or those associated with other findings may need more investigation, but isolated small ACC has an excellent prognosis.
New Treatments for Atopic Dermatitis (Eczema) in Children
Treatment for atopic dermatitis in children has advanced significantly in recent years. While moisturizers and topical steroids remain first-line treatments, newer options include non-steroidal topical medications (like crisaborole), biologic therapies (like dupilumab, approved for children 6 months and older), and JAK inhibitors. Most children's eczema is well-managed with basic skin care and mild topical treatments, but these newer options provide hope for moderate-to-severe cases.
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.
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.
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.
