Peanut allergy

I'm not allergic to peanuts, I eat peanut butter and jelly sandwiches once and awhile. Peanut allergy often presents in the first year of life, and we often wonder why that is if they haven't had any exposure and have only been consuming breast milk or formula. Should mothers who are breastfeeding and who are concerned about allergies watch their diet.
I was wondering should we completely avoid peanuts while the child is an infant and in early childhood to avoid ever developing a peanut allergy, since it usually develops early, if at all. On the other hand, it's also possible that some slight exposure may be necessary to strengthen the immune system to fight off or lessen the effects of a peanut allergy attack.
What do you think about peanut allergies?

    I"M SO GLAD we don't have a peanut allergy here.. or nut of any kind.. I think I would never sleep.. the kids at my kids school that have nut allergies have to sit at a separate table.. which at first I thought was awful, but then realized it was for their safety when I saw kids sharing their food and we had full on medical emergency within 3 minutes.. awful..

    I'm so glad though..
    I was told that you can pick up or drop allergies too.
