From what this allergist was saying, hydroylsed formula isn't sweet - it tastes very different to other formulas and is expensive as well. So that's why he suggests that if bfing is not possible, then to use soy formula. If there is a reaction to that then the hydrolysed.

Honey definitely is a different thing - it's not an allergy so you should still avoid that.

WRT to peanuts - it is very closely linked to allergies to other tree nuts so maybe that's why they call it a "nut" allergy. Dry roasted peanuts are the worst allergy trigger - and this is the type used in peanut butter. So when you are giving your child peanuts for the first time, it is best to avoid dry roasted peanuts and peanut butter. Boiled peanuts is good option as it is also soft for younger children.

Lea - as a pp said, I would think that ezcema would count as a reaction, so you would then want to avoid that food. An allergist would be able to give you more information.

Also, please bear in mind that the guidelines haven't actually changed wrt the timing of allergenic foods. It is the decision of each parent as to when to introduce things, based on all the information available.
