No: A peanut allergy could develop at any time whether peanuts are being eaten intermittently or even regularly. It's not exactly clear why peanut allergies develop, but it does require 1) exposure ie eating peanuts, 2) sensitization--the body's immune system see the peanut protein as "foreign" and 3) re-exposure---that's when symptoms occur.
