ceres, mrs. long: the peanut allergy is mainly for those mommies or even daddies who already have some kind of allergies, so when pregnant, it's advisable to avoid peanuts, eggs, milk, etc. to prevent babies from having the allergies too. you can google and look it up.
I'm avoiding peanuts now. My cousin's kids are allergic to peanuts - inherited from the mom. the eldest one cannot stand the smell of any nuts, else he'll get rashes. and worst case scenario, can lead to death
