Allergies are when the immune system immediately responds with an abnormal reaction against a foreign substance on the outside and/or inside of the body, creating antibodies as a defense. Examples include but are not limited to irritation of the skin (which is then labeled eczema even though the root cause is an allergy), inflammation, swelling, vomiting, etc. ( You can test for the antibodies in an allergy skin-prick test and/or blood test (see #7). Babies can grow out of allergies by age two and more likely by age 16 ( Allergies can be life threatening (anaphylaxis) depending on the severity of the allergy and the level of exposure. If baby is reacting indirectly through breastmilk, it can take 4-24 hours for baby to react ( If your baby is solely breastfed, a food allergy could cause a more severe reaction if/when it’s directly ingested. In these instances, an Epipen could save your baby’s life. Please note that an Epipen will only temporarily help your baby breath so they must still be rushed to the emergency room for full care. 


Eczema is the name for a group of visible skin conditions ( that occur because of what researchers currently believed to be a chronic defect in the skin barrier ( The skin conditions are a delayed response of redness, inflammation and itching (+ sometimes weeping & cracking) after being exposed to an “irritant”, “trigger” and/or “allergy” on the outside and/or inside of the body. Eczema causes delayed skin reactions of 2 hours - 3 days later or even longer if exposed through breast milk ( *As a personal note so you can be cautious of delayed reactions*Anthony reacts to directly eating soy 5-6 days later with head to toe red bumps that terribly itch. According to Seattle Children's Hospital, cow's milk is the most common eczema trigger in babies ( Eczema can go into remission stages and typically improves as a child ages. ( While eczema is not dangerous, infections (like staph infection or eczema herpeticum (herpes)) that can spread quickly through eczema can be. Eczema does not create antibodies as a defense so we cannot test for it. However, when it comes to skin irritations, both eczema triggers and allergies can be pinpointed through the process of elimination strategy (see 7 Strategies to Pinpointing the Underlying Cause(s) of Baby Skin Irritations #5). The difference in reaction times are the key clues in determining if you’re dealing with an allergy or simply with an eczema “trigger” or “irritant”. 

Reaction Times for Both

Allergies cause an immediate reaction when baby is directly exposed but can take 4-24 hours if the baby is reacting through breastmilk (

Eczema triggers on the other hand cause delayed reactions of 2 hours - 3 days later or even longer through breast milk ( According to Seattle Children's Hospital, cow's milk is the most common eczema trigger in babies (
