DS6 has to have an epipen for allergy to cashews and possibly almonds.
Interestingly, I'm allergic to mangos and highly reactive to poison ivy. These two and cashews are in the same family, and I LIVED on cashews when I was experiencing morning sickness while pregnant with him. My second choice to fight the nausea? Almonds! Coincidence? I don't think so!
DS3 doesn't seem to be allergic to anything yet, but I avoided all nuts while pregnant with him just to be safe. Of course, the chance that he's allergic to the same thing as his brother is slim. It is highly likely that he's allergic to something though. Everyone else in the family is!
