I've had 3 babies:
Baby #1: I had no cravings until the end when chocolate became my everything!! I was never a big chocolate eater until then. However, I developed an aversion to raw meat. The first time it hit was when I went to brown some hamburger for tacos and that smell when the raw meat first starts cooking almost made me lose my lunch. I also found I couldn't toucn raw chicken breasts, and this aversion has stuck with me. I want to puke handling raw chicken breasts (don't even ask me to man handle a raw turkey for Thanksgiving!).
Baby#2: I craved so much fruit, mostly mango and pineapple. I did find I once again had an aversion to meat, but in sandwhich meat form. To go to subway to get a sandwich was absolutely disgusting to me.
Baby #3: I craved so much sugar, sugar, sugar, it was horrible. I would actually sneak candy it was so bad. I was so glad when this baby was born because that overly powering sugar craving literally went away in a snap.
