Ryan is allergic to nuts. All nuts. Which means that he is also allergic to peanut butter. I have done a few tests and I don't think that Harper is allergic. Allergies can present themselves later in life, so there is still a possibility that she could be allergic.
I have found Soy Butter which is a non-peanut alternative to peanut butter. While pregnant I like to have a nice little PB&J every once in a while. I am always careful to use the knife in the non-peanut butter component of the sandwich first so that I don't get peanut butter into the other jar. I always clean the knife off too. I would just feel more comfortable having soy butter instead. That way if Harper turns out to be allergic she can still have a PB&J sandwich.
Is Soy Butter good?
Does it taste like peanut butter?
