"It's a great time to be a fetus"
That's a quote from the daily pregnancy calendar I read on iVillage.com. It also says that the peanut has been upgraded to the size of a small gerbil:
"Your baby weighs about 2.8 ounces (79 grams) and is about 4 1/2 inches from crown to rump -- roughly the size of a small gerbil. At any time, you will begin to feel fetal movement as your baby's bones harden, and she starts a big growth spurt. Your baby has plenty of room: At this point, she could fit in the palm of your hand. This is a great time to be a fetus. At any given time, she might be playing with the umbilical cord (which she's now able to grasp), putting her thumb in her mouth, or kicking at the amniotic sac."
Woo hoo. Party on.
