Your Baby

This week, your little tadpole is starting to look a little bit more human. Other exciting developments include:

Your baby's eyelids, ears, upper lip and the tip of his soon-to-be adorable button nose are forming.

Junior will also sprout webbed fingers and toes this week—which you'll be well aware of in a few months, as baby starts early gymnastics classes inside you.

Baby's tiny heart has separated into four distinct chambers and is really ticking now—at a rate of 150 beats per minute. That's more than twice your resting heart rate (even when Brad Pitt is on the screen).

Your baby is now a little more than ½ inch long, about the size of the rock in Nicole Richie's engagement ring, and is about as heavy as the check Joel Madden wrote to pay for it.
