A decade after a landmark study proved that feeding peanut products to young babies could prevent development of life-threatening allergies, new research finds the change has made a big difference in the real world.
Peanut allergies began to decline in the U.S. after guidance first issued in 2015 upended medical practice by recommending introducing the allergen to infants starting as early as 4 months. The rate of peanut allergies in children ages 0 to 3 fell by more than 27% after guidance for high-risk kids was first issued in 2015, and by more than 40% after the recommendations were expanded in 2017.
I would think that if both parents were highly allergic, you might want to give baby that first taste of peanut butter in a medical setting.
First exposure, even if anaphylactic is not as bad or life threatening. Second and subsequent exposures are rapid and pronounced.
So, if they are super high risk, then that is a good idea, but it’s not as important as avoiding nuts for someone with a previous exposure that caused a reaction.
