Baby Fungal Rash (Ringworm / Tinea)
The short answer
Despite its name, ringworm has nothing to do with worms -- it is a common, harmless fungal infection of the skin. It appears as a round or oval red patch that may have a raised, scaly border with clearing in the center. It is easily treated with antifungal cream and typically clears within 2-4 weeks.
By Age
What to expect by age
Ringworm is uncommon in very young babies but can occur if there is close contact with an infected person, pet, or contaminated surface. In young infants, any unusual rash should be seen by your pediatrician to confirm the diagnosis, since other conditions can look similar. Over-the-counter antifungal creams are generally safe for babies but check with your doctor for the right product and dosing.
As babies become more mobile and explore their environment, they have more exposure to surfaces and objects that could harbor fungal spores. Ringworm on the body (tinea corporis) appears as a round, red patch with a raised, slightly scaly edge. It is mildly contagious and spreads through direct skin contact or shared items like towels and clothing.
Toddlers in daycare are at increased risk of ringworm due to close contact with other children. Ringworm of the scalp (tinea capitis) is more common in this age group and may cause scaly patches, broken hairs, or small bald spots. Unlike body ringworm, scalp ringworm requires oral antifungal medication prescribed by your doctor, as topical creams cannot penetrate the hair follicle.
What Should You Do?
When to take action
- A single small round patch on the body that responds to antifungal cream within 1-2 weeks
- The ring-shaped rash has a clear center and raised, slightly scaly border
- The patch is not painful, just mildly itchy
- Improvement is steady after starting appropriate antifungal treatment
- The rash is not improving after 2 weeks of consistent antifungal cream application
- Scaly patches appear on the scalp with hair loss or breakage, which may need oral antifungal medication
- Multiple patches are appearing in different locations
- The rash is spreading to other family members or pets
- The affected area becomes very swollen, boggy, tender, and oozing (a kerion), which is an intense inflammatory reaction requiring prescription treatment
- Your child develops a widespread rash with fever, which may not be ringworm and needs prompt evaluation

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 Blister on Lip from Nursing
A nursing blister (also called a suck callus) is a small, painless blister or thickened patch on your baby's upper lip caused by the friction of latching during breastfeeding or bottle feeding. It is completely harmless, does not hurt your baby, and does not need any treatment. These are very common in newborns and typically come and go in the early weeks.
Baby Chin Rash from Drooling
Drool rash is extremely common and appears as red, irritated, or slightly bumpy skin on the chin, cheeks, neck, and chest where drool sits. It is caused by the constant moisture and digestive enzymes in saliva irritating the skin. Keeping the area dry and applying a barrier like petroleum jelly before drool exposure is the most effective treatment.
Baby Dry Patches on Cheeks
Dry patches on your baby's cheeks are very common, especially during cold or dry weather. Baby skin is much thinner and more sensitive than adult skin and loses moisture easily. In most cases, regular application of a gentle, fragrance-free moisturizer is all that is needed. If patches are red, rough, or itchy, mild eczema may be the cause.
Baby Ingrown Toenail
Ingrown toenails are fairly common in babies and toddlers, especially on the big toe. Baby toenails are soft and can easily curve into the surrounding skin. Most mild cases improve with warm soaks and gentle care. If the toe becomes very red, swollen, or shows signs of infection, your pediatrician can help with treatment.
Baby Nail Peeling or Splitting
Peeling or splitting nails in babies are very common and usually harmless. Baby nails are extremely thin and soft, making them prone to peeling, especially from normal wear and moisture exposure. This typically improves as your child grows and their nails become stronger. Keep nails trimmed short and moisturize the nail area gently.
