Baby skin is sensitive and changes frequently. If you are noticing sandpaper rash and scarlet fever in baby, here is what you need to know.
The short answer
A rash that feels like sandpaper, especially with fever and sore throat, may be scarlet fever (scarlatina). Scarlet fever is caused by group A streptococcus bacteria and is treatable with antibiotics. While the name sounds scary, it is essentially a strep throat infection with a rash and responds well to treatment. It is most common in children over 2 years old but can occasionally occur in younger children.
Key takeaways
- A rash that feels like sandpaper, especially with fever and sore throat, may be scarlet fever (scarlatina). Scarlet fever is caused by group A streptococcus bacteria and is treatable with antibiotics. While the name sounds scary, it is essentially a strep throat infection with a rash and responds well to treatment. It is most common in children over 2 years old but can occasionally occur in younger children.
- Usually normal when: There is no truly "normal" version of scarlet fever, as it always requires antibiotic treatment to prevent complications
- Call your doctor if: Your child has a sandpaper rash with high fever and sore throat and should be seen the same day for a strep test and antibiotics
- 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.”
Parents everywhere have the same worry. You are doing the right thing by looking into it.
What Parents Should Know
According to AAP, CDC, NIH guidelines, a rash that feels like sandpaper, especially with fever and sore throat, may be scarlet fever (scarlatina). Scarlet fever is caused by group A streptococcus bacteria and is treatable with antibiotics. While the name sounds scary, it is essentially a strep throat infection with a rash and responds well to treatment. It is most common in children over 2 years old but can occasionally occur in younger children. At 0-3 months, scarlet fever is extremely rare in babies under 3 months because they still have some protective antibodies from their mother. If a newborn develops a widespread sandpaper-like rash with fever, other causes should be considered and the baby should be evaluated urgently. It is generally considered normal when there is no truly "normal" version of scarlet fever, as it always requires antibiotic treatment to prevent complications. However, you should contact your pediatrician promptly if your child has a sandpaper rash with high fever and sore throat and should be seen the same day for a strep test and antibiotics.
Normal vs. Concerning
By Age
What to expect by age
0-3 months
Scarlet fever is extremely rare in babies under 3 months because they still have some protective antibodies from their mother. If a newborn develops a widespread sandpaper-like rash with fever, other causes should be considered and the baby should be evaluated urgently.
3-6 months
Scarlet fever remains uncommon in this age group. However, if your baby develops a diffuse, rough-textured rash with fever, it is important to have them evaluated. Other conditions, such as viral rashes or drug reactions, are more likely at this age but should still be assessed.
6-12 months
While still less common than in older children, scarlet fever can occur at this age. The rash typically starts on the trunk and spreads to the arms and legs, feeling rough like sandpaper. The skin creases (armpits, elbows, groin) may appear darker red. A strawberry tongue (red and bumpy) is another classic sign.
12-24 months
Toddlers in group care settings are at higher risk for strep infections. Scarlet fever causes a sandpaper rash that blanches when pressed, along with fever, sore throat, and sometimes vomiting. After treatment with antibiotics, the skin may peel as it heals, particularly on the fingertips. Your child is no longer contagious after 24 hours on antibiotics.
What to Tell Your Pediatrician
- Describe when you first noticed sandpaper rash and scarlet fever in baby and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if your child develops a rash that feels like sandpaper, even without fever or sore throat.
- Mention if your child has been exposed to someone diagnosed with scarlet fever or strep throat.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- There is no truly "normal" version of scarlet fever, as it always requires antibiotic treatment to prevent complications
- Your child develops a rash that feels like sandpaper, even without fever or sore throat
- Your child has been exposed to someone diagnosed with scarlet fever or strep throat
- Skin peeling occurs on the hands and feet after a recent illness
- Your child has a sandpaper rash with high fever and sore throat and should be seen the same day for a strep test and antibiotics
- Your child was diagnosed with scarlet fever but symptoms are worsening despite 48 hours on antibiotics
- Your child develops joint swelling, dark urine, or chest pain after a strep infection, which could indicate a post-strep complication
What You Can Do at Home
- Keep track of when you notice sandpaper rash and scarlet fever in baby — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that there is no truly "normal" version of scarlet fever, as it always requires antibiotic treatment to prevent complications — this is generally within the range of normal.
- At 0-3 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 your child has a sandpaper rash with high fever and sore throat and should be seen the same day for a strep test and antibiotics.
Related Conditions
Baby Rough or Bumpy Skin Texture
Rough or bumpy skin in babies is very common and usually caused by dry skin, eczema, or keratosis pilaris (tiny bumps from keratin buildup in hair follicles). These conditions are harmless and manageable with regular moisturizing. Rarely, a sandpaper-like rash with fever could indicate scarlet fever, which needs medical attention.
Baby Rash Accompanied by Fever
Rashes that occur with or after a fever are very common in babies and are most often caused by viral infections. Roseola is the classic example, where a rash appears after the fever breaks. While most causes are benign, a rash with fever should always be monitored carefully, and a non-blanching rash with fever needs immediate medical attention.

Baby Rough or Bumpy Skin Texture
Rough or bumpy skin in babies is very common and usually caused by dry skin, eczema, or keratosis pilaris (tiny bumps from keratin buildup in hair follicles). These conditions are harmless and manageable with regular moisturizing. Rarely, a sandpaper-like rash with fever could indicate scarlet fever, which needs medical attention.

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.
