That, and the fact that diagnosis and treatment have gotten a lot better. I have to wonder how many unexplained deaths of children in years past were actually peanut or other allergies. If children are exposed to peanuts at an early age, does that cause the allergy, or were those deaths written off as SIDS before?
No--SIDS and severe peanut allergies occur at different ages. Asthma and peanut anaphylaxis have increased in absolute terms. No question. See above post about soy bean formula possibly being the sensitizing culprit.
