Scabies Symptoms in Babies
The short answer
Scabies is a skin condition caused by tiny mites (Sarcoptes scabiei) that burrow into the skin and cause intense itching. In babies, scabies often looks different than in adults - it can appear on the face, scalp, palms, and soles, which are unusual locations in older children and adults. The rash consists of small red bumps, burrow tracks, and sometimes blisters. Scabies requires prescription treatment (typically permethrin cream) and all household contacts should be treated simultaneously.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
0-6 months
Scabies in young infants can be difficult to diagnose because it looks different than in older children. In babies, the rash commonly appears on the face, scalp, neck, palms, and soles - areas rarely affected in adults. The rash may look like small red bumps, tiny blisters, or widespread eczema-like patches. Babies may be irritable and have trouble sleeping due to intense itching, which is typically worse at night. See your pediatrician for diagnosis; they may examine the skin with a magnifier or do a skin scraping.
6-12 months
Babies this age with scabies may scratch at affected areas, creating raw or crusted patches that can become secondarily infected with bacteria. The rash may spread widely over the body. Treatment with 5% permethrin cream is approved for use in infants 2 months and older. The cream must be applied from the neck down (and on the scalp and face in babies) and left on for 8-14 hours before washing off. All family members and close contacts should be treated at the same time, even if they have no symptoms, as scabies has a 4-6 week incubation period.
12-36 months
Toddlers with scabies often present with itching in the finger webs, wrists, ankles, and diaper area. Daycare attendance increases exposure risk. Itching may persist for 2-4 weeks after successful treatment due to an ongoing allergic reaction to dead mites; this does not mean treatment failed. Retreatment is typically recommended 1-2 weeks after the first application. Wash all bedding, clothing, and towels in hot water and dry on high heat. Items that cannot be washed can be sealed in a plastic bag for 72 hours.
What Should You Do?
When to take action
- Itching gradually decreases over 2-4 weeks after treatment - some residual itching is expected.
- A few new bumps appear in the first week after treatment as existing eggs hatch before dying.
- Other family members who were treated preventively never develop symptoms.
- You suspect scabies but are not sure - accurate diagnosis is important before treatment.
- The rash and itching are not improving 2-3 weeks after completing two rounds of treatment.
- Your baby has widespread or crusted (Norwegian) scabies, which may require oral treatment.
- The scabies rash area becomes hot, swollen, red, and oozing, suggesting a secondary bacterial infection.
- Your baby develops fever along with infected-looking skin lesions.
- Your baby has an adverse reaction to treatment such as a severe rash or swelling.

Related Skin Concerns
Ringworm in Babies from Daycare
Ringworm (tinea) is a common fungal skin infection, not a worm. It appears as a red, scaly, circular patch with a clearer center and is very contagious through direct skin contact or shared items. Daycare settings are common sources due to close contact between children. Ringworm is treatable with antifungal creams, and most cases clear within 2-4 weeks of consistent treatment.
Baby Hives (Urticaria)
Hives are raised, red, itchy welts that can appear suddenly on your baby's skin. They are most often caused by a viral infection or an allergic reaction to food, medication, or an insect bite. While they can look alarming, hives are usually harmless and resolve on their own, though any breathing difficulty needs immediate emergency care.
Baby Rash from New Laundry Detergent
Rashes from laundry detergent are a form of contact dermatitis and appear as red, itchy patches where clothing touches the skin. Baby skin is thinner and more sensitive than adult skin, making it more prone to irritation from fragrances, dyes, and chemicals in detergents. Switching to a fragrance-free, dye-free detergent and rewashing affected clothing usually resolves the rash within a few days.
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.
