Red Blotchy Rash on My Newborn
The short answer
Erythema toxicum is a very common, harmless newborn rash that appears as red blotches with small white or yellow bumps in the center. Despite its alarming name, it is completely benign, affects about half of all full-term newborns, and clears up on its own within a week or two without any treatment.
By Age
What to expect by age
Erythema toxicum rarely appears on the first day of life. Most babies are born with clear skin, and the rash develops over the next 24-48 hours. It often starts on the face or trunk and can look quite dramatic when it first appears, causing understandable concern for new parents.
This is the peak time for erythema toxicum to appear. The rash consists of red patches or blotches with tiny white or yellow bumps in the center, resembling flea bites or hives. It can appear anywhere on the body except the palms and soles. The rash may come and go, appearing in different spots throughout the day, which is completely normal.
Erythema toxicum typically begins to fade during this period without any treatment. The red blotches lighten, and the white bumps disappear. The rash does not itch, hurt, or bother your baby in any way. No creams, ointments, or medications are needed. Simply continue regular gentle bathing and skin care.
By this age, erythema toxicum has usually completely resolved. If a blotchy rash appears for the first time after two weeks of age, it is not erythema toxicum and should be evaluated by your pediatrician. Common considerations at this age include baby acne, eczema, or viral rashes.
What Should You Do?
When to take action
- Red blotchy patches with small white or yellow bumps appearing on day 2-5 of life
- The rash comes and goes, appearing in different locations throughout the day
- The rash is limited to the face, trunk, arms, and legs but does not involve the palms or soles
- Your baby is otherwise well, feeding normally, and has no fever or signs of illness
- Gradual fading and complete resolution within 1-2 weeks without any treatment
- The rash persists beyond 2 weeks of age or seems to be worsening rather than improving
- You are unsure if the rash is erythema toxicum or another newborn rash condition
- The bumps seem to be forming large pustules or blisters rather than tiny pinpoint bumps
- Your baby develops a fever (rectal temperature over 100.4°F/38°C) along with the rash
- The rash is accompanied by poor feeding, lethargy, irritability, or other signs of illness
- Blisters, skin peeling, or purplish spots develop along with the rash

Related Skin Concerns
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.
