With DS I wanted cheeseburgers and fries with salt/vinegar. I also loved pickles, onions mixed with mustard and microwaved for 30 seconds or so.
DD1- I didn't give birth to her but when she came home I found that I ended up eating babyfood with her because she wouldn't eat unless you did. Banana Cream Pie rules.
DD2- Ice, ice and more ice. DH bought 8 icetrays at the dollar store just to try to keep up. Chicken balls and rice were a big favorite and BK fries.
I had wicked morning sickness with both pregnancies, I could hardly eat anything for about three months but I certainly made up for it later. I also had bad heartburn and both were born with full heads of thick hair.
