During pregnancy, I think I subconsciously "steal" other people's cravings.
My grandmother told me that she was craving mashed potatoes and root beer. Not two things I normally eat, but for the next week it was all I wanted.
A coworker had a craving for radishes. Normally I didn't really like or dislike them, but she started me on a 3-week radish binge.
Same thing with tacos, pineapple, and V8.
