That is exactly the problem Curly - there is no rhyme or reason to nut allergy. Early or late introduction seems to make no difference. Family history is just a precaution for those who may be prone. For the rest of us it is luck of the draw and there is nothing that we can do / not do to prevent it if your child happens to be sensitive or anaphylactic.

The ramifications of allergy is huge and underestimated. The impact on the family is significant. There is no going out for dinner without considering the risk of exposure to the allergen, for example. There is the need to carry and use adrenaline to manage the severe reactions.

Parents need to make the decision of when to introduce potential allergens based on their own comfort level and any family history.
