Baby waving and other progress

so, we went for our 8 week ultrasound last week and got to see the baby again. i'm not sure if technically it's a embryo, fetus, or what....we'll just stick with the always appropriate title of "baby." this time, the image we could see was much more distinct. we could see two parts, a head and a body, and two little buds that the doctor informed us were arms. right in the center we could see the heart beating. and it kind of looked like the baby was waving to us, moving its arms around. it is WILD to me how much happens in this short of time.
i looked on the internet today and the baby is now the size of a grape (i love the fruit references). it has earlobes, all its joints are working, and the heart now has all 4 chambers. i am in constant amazement that all this is going on inside of me. and so far, it's been pretty easy. i basically eat all the time to combat the ridiculous feelings of hunger, so that's not too bad.
i agree with joe that i cannot wait to start telling people. it feels sort of unfair to have this much joy in our lives and keep it all to ourselves.....
