Baby skin is sensitive and changes frequently. If you are noticing molluscum contagiosum in babies & toddlers, here is what you need to know.
The short answer
Molluscum contagiosum causes small, firm, dome-shaped bumps with a tiny dimple in the center. It is caused by a common, harmless virus and is very common in young children. While it looks unusual, it is not dangerous and the bumps eventually go away on their own, though it can take several months to over a year.
Key takeaways
- Molluscum contagiosum causes small, firm, dome-shaped bumps with a tiny dimple in the center. It is caused by a common, harmless virus and is very common in young children. While it looks unusual, it is not dangerous and the bumps eventually go away on their own, though it can take several months to over a year.
- Usually normal when: Small, painless, dome-shaped bumps with a characteristic central dimple
- Call your doctor if: A molluscum bump becomes very red, swollen, warm, and painful, suggesting a 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, CDC guidelines, molluscum contagiosum causes small, firm, dome-shaped bumps with a tiny dimple in the center. It is caused by a common, harmless virus and is very common in young children. While it looks unusual, it is not dangerous and the bumps eventually go away on their own, though it can take several months to over a year. At 0-6 months, molluscum is uncommon in babies under 6 months because they still have some protection from maternal antibodies. If small bumps appear in very young infants, it is worth having your pediatrician confirm the diagnosis, as other conditions can look similar at this age. It is generally considered normal when small, painless, dome-shaped bumps with a characteristic central dimple. However, you should contact your pediatrician promptly if a molluscum bump becomes very red, swollen, warm, and painful, suggesting a secondary bacterial infection.
Normal vs. Concerning
By Age
What to expect by age
0-6 months
Molluscum is uncommon in babies under 6 months because they still have some protection from maternal antibodies. If small bumps appear in very young infants, it is worth having your pediatrician confirm the diagnosis, as other conditions can look similar at this age.
6-12 months
Babies in this age range can contract molluscum through skin-to-skin contact, shared towels, or from an older sibling. The bumps are small, flesh-colored or pearly white, and painless. They may appear in clusters, commonly on the trunk, arms, legs, or face. They do not require treatment but can spread to nearby skin.
1-3 years
This is a very common age for molluscum, particularly in children who attend daycare. The bumps can persist for 6-18 months on average before the immune system clears the virus. New bumps may continue to appear even as older ones are resolving. Keeping the bumps covered with clothing or bandages can reduce spread to others and to other areas of your child's body.
What to Tell Your Pediatrician
- Describe when you first noticed molluscum contagiosum in babies & toddlers and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if bumps are spreading rapidly or appearing in very large numbers.
- Mention if molluscum bumps are in sensitive areas like the eyelids or genital region.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Small, painless, dome-shaped bumps with a characteristic central dimple
- Bumps that are flesh-colored, pearly, or slightly pink and scattered on the trunk or limbs
- New bumps appearing slowly over weeks while older bumps start to flatten
- The bumps becoming slightly red or inflamed right before they clear, which is a sign the immune system is fighting the virus
- Bumps are spreading rapidly or appearing in very large numbers
- Molluscum bumps are in sensitive areas like the eyelids or genital region
- The skin around the bumps is becoming very itchy, red, or developing eczema-like changes
- You would like to discuss treatment options to speed clearance
- A molluscum bump becomes very red, swollen, warm, and painful, suggesting a secondary bacterial infection
- Your child develops a fever along with spreading redness around the bumps
What You Can Do at Home
- Keep track of when you notice molluscum contagiosum in babies & toddlers — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that small, painless, dome-shaped bumps with a characteristic central dimple — 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 a molluscum bump becomes very red, swollen, warm, and painful, suggesting a 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.
