Baby skin is sensitive and changes frequently. If you are noticing eczema and asthma link (atopic march), here is what you need to know.
The short answer
The "atopic march" describes a pattern where eczema in infancy is followed by food allergies, hay fever, and asthma later in childhood. While having eczema does increase the risk, it is not a certainty: most children with eczema do not develop all these conditions. Early, effective eczema treatment and allergen introduction may help reduce the risk.
Key takeaways
- The "atopic march" describes a pattern where eczema in infancy is followed by food allergies, hay fever, and asthma later in childhood. While having eczema does increase the risk, it is not a certainty: most children with eczema do not develop all these conditions. Early, effective eczema treatment and allergen introduction may help reduce the risk.
- Usually normal when: Your baby has eczema but shows no signs of food allergies or breathing issues
- Call your doctor if: Your baby has a severe allergic reaction (hives, vomiting, difficulty breathing) after eating a food
- 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, NIH guidelines, the "atopic march" describes a pattern where eczema in infancy is followed by food allergies, hay fever, and asthma later in childhood. While having eczema does increase the risk, it is not a certainty: most children with eczema do not develop all these conditions. Early, effective eczema treatment and allergen introduction may help reduce the risk. At 0-3 months, eczema is often the first sign of the atopic march, commonly appearing in the first few months of life. Research suggests that aggressive early treatment of eczema, including maintaining a strong skin barrier with consistent moisturizing, may help reduce the risk of developing food allergies and asthma later. This is an active area of ongoing research. It is generally considered normal when your baby has eczema but shows no signs of food allergies or breathing issues. However, you should contact your pediatrician promptly if your baby has a severe allergic reaction (hives, vomiting, difficulty breathing) after eating a food.
Normal vs. Concerning
By Age
What to expect by age
0-3 months
Eczema is often the first sign of the atopic march, commonly appearing in the first few months of life. Research suggests that aggressive early treatment of eczema, including maintaining a strong skin barrier with consistent moisturizing, may help reduce the risk of developing food allergies and asthma later. This is an active area of ongoing research.
3-6 months
Studies suggest that food allergens may enter through broken eczema skin and trigger allergic sensitization. This is why some experts recommend early introduction of common allergens (like peanut) alongside proactive eczema management. The LEAP study showed that early peanut introduction reduced peanut allergy in high-risk infants with eczema.
6-12 months
If your baby has moderate to severe eczema, your pediatrician may recommend allergy testing before introducing high-risk foods, or may encourage early introduction under guidance. Not all babies with eczema will develop food allergies, but monitoring for reactions when introducing new foods is wise.
12-24 months
By toddlerhood, some children with eczema begin to show signs of respiratory allergies or wheezing. About 30% of children with eczema go on to develop asthma, compared to about 10% of the general population. If your toddler has eczema and begins wheezing, coughing at night, or having breathing trouble, discuss this with your pediatrician.
What to Tell Your Pediatrician
- Describe when you first noticed eczema and asthma link (atopic march) and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if you want to discuss the atopic march and what you can do to reduce your baby's risk.
- Mention if your baby has moderate to severe eczema and you are starting solid foods.
- 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
- Your baby has eczema but shows no signs of food allergies or breathing issues
- Eczema is well-controlled with moisturizing and your baby is thriving overall
- A family history of eczema, asthma, or allergies is present but your baby is developing normally
- You want to discuss the atopic march and what you can do to reduce your baby's risk
- Your baby has moderate to severe eczema and you are starting solid foods
- You notice your baby wheezing, coughing repeatedly, or having breathing difficulty during colds
- You want to discuss allergy testing given your baby's eczema history
- Your baby has a severe allergic reaction (hives, vomiting, difficulty breathing) after eating a food
- Your baby is wheezing or having significant breathing difficulty
What You Can Do at Home
- Keep track of when you notice eczema and asthma link (atopic march) — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that your baby has eczema but shows no signs of food allergies or breathing issues — 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 baby has a severe allergic reaction (hives, vomiting, difficulty breathing) after eating a food.
Related Conditions
Baby Eczema (Atopic Dermatitis)
Baby eczema is extremely common, affecting up to 20% of infants, and is not caused by anything you did wrong. It shows up as dry, red, itchy patches and is very manageable with consistent moisturizing and gentle skin care. Most children outgrow it by school age.
Eczema and Food Allergy Link
Research shows a strong connection between eczema (atopic dermatitis) and food allergies in babies. Babies with moderate-to-severe eczema, especially appearing before 6 months, have a significantly higher risk of developing food allergies. Current guidelines recommend early introduction of allergenic foods (particularly peanut) starting around 4-6 months for high-risk babies with eczema, as early exposure may actually help prevent food allergies.
Identifying Eczema Triggers in Baby
Identifying your baby's specific eczema triggers can significantly improve flare management. Common triggers include dry air, fragranced products, certain fabrics, sweat, saliva, specific foods, dust mites, pet dander, and stress. Keeping a trigger diary can help you spot patterns. Not every baby has the same triggers, so finding your child's unique set takes some detective work.

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.
