Any allergy can be grown out of ....and different ones acquired.  Also, I would definately stay away from peanuts for your little one, but from what I’ve been told after going from 1. no reaction at all from wasps to 2. anaphalactic shock  they say this is more likely.  To go from no reaction to shock, that if you have a mild reaction that’s a safer "bet" to not having a severe allergy.  But I have also heard of reactions growing with each exposure.  I’m still dealing with this allergy.  This time of year is not very fun for me as the wasp, yellow jacket, hornet population is desperate what with food running out and cold weather they get quite aggressive and I stay in the house!!  Luckily we are also harvesting our apple trees and garden and I have much to keep me busy indoors!  Good luck with these allergies.  I know they are not fun.  Julia
