Well after I had my first daughter I ate nothing but ice, I was eating that much my OH was worried I'd grind my teeth down to nothing. I now put cordial/flavoured drink in the freezer to make it ice so I can eat it. I know that's not too weird. I haven't had any weird cravings but have heard of it before. When my cousin was 2-3 years old she use to eat egg shells and tea leaves out of the tea bags.
