Where does the peanut and egg allergy come from? My understanding is that peanut oil and egg albumin are ingredients in many common medicines given early to infants.. is there any chance that could be contributing?
Egg albumin is also interesting because the vast majority of kids outgrow it. My toddler has a peanut allergy but has already outgrown his egg albumin allergy.
There are other commenters warning about skin exposure before dietary exposure. If that’s true then it would make sense.
Interesting point about the skin exposure, I’ll go back and review those comments. Evolutionarily/practically i would think it’s tough to get oral exposure to something prior to skin exposure (it hits your mouth/hands/face before your stomach), unless the breastmilk vector you mention is critical
