I thought it was 2 years for peanut butter? Maybe I'm confusing it with other stuff though LOL.

When I trialled peanut butter with Matilda, I tried a quarter of a peanut butter & jam sandwich (the american in me :P) she didn't like it. So I tried it again later, and she still doesn't like it. Matilda didn't test positive to peanuts when she had her allergy testing.. so with Jovie I was planning on the same thing, trialling 1/4 sandwich and seeing how she goes.

With allergies its either an instant reaction, or gradual... so start with a tiny amount and then the next day a bit more etc etc...
