Fingerprints have formed on your baby's tiny fingertips, his/her veins and organs are clearly visible through the still-thin skin, and the body is starting to catch up with the head. Your baby is almost 3 inches long (the size of a medium shrimp) and weighs nearly an ounce.
I love the food analagies -- it definitely makes it easier to visualize just how much things are changing each week! I also read that by 13 weeks, every organ and system is pretty much formed (just VERY tiny), and that the next 27 weeks are all about growing. Todd and I have started thinking about names, but nothing too serious until we find out if it's a boy or a girl (probably the end of September).
Since all of this started, I've had a few cravings: anything cheese, coke icees (no more than one per week), and yellow cake with chocolate frosting. I've also loved salty things more than sweet so far, and pretty much survived all summer on Goldfish crackers!
