Eczema (Atopic Dermatitis) in Babies & Toddlers
Content reviewed against published AAP, NIH, NHS guidelines
Last reviewed:
Eczema (atopic dermatitis) is the most common chronic skin condition in children, affecting up to 20% of infants. It causes dry, itchy, inflamed patches of skin. In babies, it typically appears on the face and scalp first, then spreads to body creases as the child grows. While eczema cannot be cured, it can be well managed and most children outgrow it by school age.
Key takeaways
- Eczema (atopic dermatitis) is the most common chronic skin condition in children, affecting up to 20% of infants.
- Most common cause: Atopic dermatitis (genetic/immune dysfunction of skin barrier)
- Emergency: Rapidly spreading clustered blisters/erosions on eczema (eczema herpeticum) with fever
- Home care: Moisturize liberally and frequently — apply thick fragrance-free emollient at least twice daily and after every bath
Possible Causes
When to Seek Help
Emergency — Call 911 or go to ER:
- Rapidly spreading clustered blisters/erosions on eczema (eczema herpeticum) with fever
- Widespread infected eczema with high fever and child very unwell
- Severe swelling of face or eyelids with eczema and fever
Urgent — See doctor today:
- Suspected eczema herpeticum (punched-out blisters/erosions)
- Eczema with spreading bacterial infection (increasing redness, warmth, pus, red streaks)
- Severe eczema preventing sleep for multiple nights with extreme distress
Same-day appointment:
- Eczema flare not responding to usual emollient treatment
- Possible infected eczema (weeping, yellow crusting)
- New severe eczema needing diagnosis and management plan
- Eczema significantly affecting feeding or daily activities
Monitor at home:
- Mild eczema responding well to regular moisturizing
- Known eczema with mild seasonal flare
- Dry patches on cheeks in young infant without distress
- Well-managed eczema with routine follow-up due
By Age
0-2 months
Normal: Mild dry patches on cheeks or scalp are very common. Some dryness and flaking is normal in newborns as skin adapts to outside environment. Seborrheic dermatitis (cradle cap) may overlap.
Worry if: Widespread eczema with oozing, crusting, or signs of infection. Eczema preventing comfortable feeding or sleep. Tiny clustered blisters on eczema patches (eczema herpeticum — needs urgent treatment).
2-6 months
Normal: This is the peak onset age for infant eczema. Red, dry, itchy patches on cheeks, forehead, and scalp are classic. Mild-moderate eczema responding to moisturizing is common.
Worry if: Severe eczema unresponsive to regular moisturizing. Eczema with punched-out blisters (eczema herpeticum). Weeping, yellow-crusted areas (bacterial superinfection). Baby unable to sleep due to itching.
6-12 months
Normal: Eczema may spread to arms, legs, and trunk. Patches in elbow and knee creases begin. Flares with teething, viral illnesses, or weather changes are common. Mild-moderate disease managed with emollients is typical.
Worry if: Eczema not responding to prescribed treatments. Signs of infection: increased redness, warmth, pus, fever. Widespread flare with baby extremely distressed. Failure to thrive alongside eczema (food allergy concern).
1-3 years
Normal: Classic flexural distribution (elbow creases, behind knees, wrists, ankles). Flares and remissions are normal. Many children begin to improve between ages 2-5.
Worry if: Eczema that is worsening despite good management. Widespread infection of eczema patches. Eczema severely impacting quality of life or sleep. Suspected eczema herpeticum (rapidly spreading vesicles on eczema).
Home Care
- Moisturize liberally and frequently — apply thick fragrance-free emollient at least twice daily and after every bath
- Use "soak and seal" method: bathe in lukewarm water for 5-10 minutes, pat skin damp (not dry), immediately apply emollient
- Avoid soap — use soap-free cleansers or emollient wash instead
- Keep baths lukewarm and brief (5-10 minutes)
- Dress baby in soft, 100% cotton clothing — avoid wool and synthetic fabrics
- Keep nails short and consider cotton scratch mittens for infants to prevent damage from scratching
- Use fragrance-free laundry detergent and skip fabric softener
- Apply prescribed topical corticosteroids as directed for flares (do not fear appropriate use)
- Maintain cool room temperature — overheating worsens itch
- Consider wet wrapping for severe flares (apply emollient, then damp layer, then dry layer)

Bottom line
Most cases of eczema (atopic dermatitis) in babies are not emergencies. However, seek immediate care if rapidly spreading clustered blisters/erosions on eczema (eczema herpeticum) with fever.
Trust your instincts. If something feels wrong, reach out to your pediatrician. Worrying about your baby means you care — that is a good thing.
