Eczema (Atopic Dermatitis) in Babies and Children
Content reviewed against published AAP, NIH, AAP, NIH guidelines
Last reviewed:
Eczema (atopic dermatitis) is a chronic, relapsing inflammatory skin condition that affects up to 20% of children. It causes dry, itchy, red, and inflamed patches of skin. It typically begins in infancy (60% develop it in the first year) and is part of the "atopic triad" along with asthma and allergic rhinitis. While there is no cure, proper management can control symptoms effectively.
Key takeaways
- Eczema (atopic dermatitis) is a chronic, relapsing inflammatory skin condition that affects up to 20% of children.
- Duration: Eczema is a chronic, relapsing condition. Approximately 60-70% of children with eczema will experience significant improvement or resolution by adolescence. However, 30-40% will have eczema into adulthood. Management is lifelong for those with persistent disease.
- Go to ER if: Eczema herpeticum — widespread small, painful, punched-out blisters or erosions with fever (herpes virus on eczema skin — medical emergency)
- No vaccine currently available
Symptoms
How It Presents by Age
0-6 months
Typically appears on cheeks, forehead, and scalp as red, weeping patches. May also affect outer arms and legs. Usually spares the diaper area (moisture protects). Can be confused with cradle cap or seborrheic dermatitis.
Risk level: Low (but impacts quality of life and sleep)
6-12 months
Cheeks, scalp, and extensor surfaces (outer arms and legs) remain most affected. Crawling may worsen knee involvement. Intense scratching begins as motor skills develop.
Risk level: Low
1-3 years
Eczema shifts to classic flexural distribution — inside elbows, behind knees, wrists, ankles, and neck creases. May affect hands. Scratching and sleep disturbance are major issues.
Risk level: Low
3-5 years
Flexural pattern continues. Skin may become thickened (lichenified) in chronic areas. Some children outgrow eczema by age 5, while others have lifelong disease. Risk of "atopic march" to asthma/allergies.
Risk level: Low
Treatment
Daily moisturizing (emollient therapy)
The cornerstone of eczema management. Apply thick, fragrance-free moisturizer (ointment or cream) at least twice daily and immediately after bathing. Emollients repair the skin barrier and reduce flare frequency.
Topical corticosteroids
First-line anti-inflammatory treatment for flares. Low-potency (hydrocortisone 1-2.5%) for face and skin folds. Medium-potency (triamcinolone 0.1%) for body. Apply once or twice daily to active patches for 7-14 days until clear.
Topical calcineurin inhibitors
Tacrolimus (Protopic) or pimecrolimus (Elidel) for sensitive areas (face, skin folds) or for long-term maintenance. Steroid-sparing alternative. FDA-approved for age 2+.
Wet wrap therapy
For severe flares: apply medication and moisturizer, cover with damp layer of clothing or gauze, then a dry layer over top. Worn for 2-6 hours or overnight. Dramatically reduces inflammation and itching.
Bleach baths
Add 1/4-1/2 cup of regular (non-concentrated) bleach to a full bathtub, soak 5-10 minutes, 2-3 times per week. Reduces Staphylococcus aureus colonization (present on 90% of eczema skin) and decreases flares.
Systemic therapy (severe cases)
Dupilumab (Dupixent) approved for ages 6 months+ with moderate-to-severe eczema. Other options include cyclosporine, methotrexate, or JAK inhibitors for refractory disease.
Home Care
- Moisturize at least twice daily with fragrance-free ointment or cream (Vaseline, CeraVe, Vanicream)
- Bathe in lukewarm water for 5-10 minutes daily (soak and seal method)
- Apply moisturizer within 3 minutes of bathing while skin is still damp
- Dress baby in soft, breathable cotton clothing
- Keep fingernails very short and consider cotton mittens at night
- Use fragrance-free, dye-free laundry detergent
- Keep home temperature cool and humidity at 40-50%
- Identify and avoid individual triggers (common: heat, sweat, rough fabrics, stress)
- Use fragrance-free, gentle cleansers (not soap)
- Consider dilute bleach baths 2-3 times per week for infected-appearing eczema
When to Worry
Go to the ER if:
- Eczema herpeticum — widespread small, painful, punched-out blisters or erosions with fever (herpes virus on eczema skin — medical emergency)
- Severe bacterial skin infection with fever and rapidly spreading redness
- Extensive skin breakdown with signs of dehydration
- Severe allergic reaction after starting new eczema medication
Call your doctor if:
- Eczema is not controlled with over-the-counter moisturizers
- Signs of skin infection (honey crusting, pus, increased redness/warmth)
- Eczema is severely disrupting sleep
- Weeping or oozing from patches
- Concern about food allergy trigger (especially if under 6 months)
- Need for prescription topical steroids or other treatments
- Eczema is spreading or worsening significantly
Keep an eye on:
- Eczema becomes weepy, crusted, or looks infected (honey-colored crusts)
- Small, clustered painful blisters (possible eczema herpeticum — herpes virus)
- Eczema is not responding to prescribed treatments
- Child is not sleeping due to severe itching
- Eczema is widespread and significantly impacting quality of life
- Fever with worsening eczema (infection)
Prevention
- Daily emollient application from birth may prevent eczema in high-risk infants (family history of atopy)
- Breastfeeding may be mildly protective
- Early introduction of allergenic foods (peanut, egg) at 4-6 months in infants with eczema may prevent food allergy
- Avoid known triggers once identified
- Maintain skin barrier with daily moisturizing even when clear
- Proactive treatment of early flares prevents escalation
Contagion & Incubation
Incubation
Not applicable — eczema is a chronic condition, not an infection. Onset typically occurs between 2-6 months of age.
Contagious for
Not contagious at any time.
Duration
Eczema is a chronic, relapsing condition. Approximately 60-70% of children with eczema will experience significant improvement or resolution by adolescence. However, 30-40% will have eczema into adulthood. Management is lifelong for those with persistent disease.

Bottom line
Eczema (Atopic Dermatitis) is treatable with appropriate medical care. Seek emergency care if eczema herpeticum — widespread small, painful, punched-out blisters or erosions with fever (herpes virus on eczema skin — medical emergency).
Trust your instincts. If something feels wrong, reach out to your pediatrician. Worrying about your baby means you care — that is a good thing.
