With my first, I craved turkey sandwiches. I had not been particularly fond of them before and I can't say that I had ever ordered one from a deli, but I couldn't get enough. They had to have the thin sliced turkey - 3 slices, an inch of lettuce, yellow mustard and toasted white bread. DH came in one day and started laughing. I was standing at ready at the counter looking at all the ingredients laid out carefully on the counter, in order and lined up perfectly. He saw me standing there and said, "What are you doing?" I said, "Waiting on the toast, it's in the oven." I ate them three meals a day for several weeks.
When my DW was expecting, I did not crave anything...weird????
