Baby's Development at Week 7

We thought we'd update you on what's developing with our baby based on a book we got called What to Expect When You're Expecting by Heidi Murkoff and Sharon Mazel. Here's what it says about Week 7 (which is where I'm at now):

"Here's an amazing fact about your baby right now: He or she is 10,000 times bigger now than at conception - about the size of a blueberry. A lot of that growth is concentrated on the head (new brain cells are being generated at the rate of 100 cells per minute). Your baby's mouth and tongue are forming this week and so are his or her arm and leg buds, which are beginning to sprout into paddle-like appendages and to divide into hand, arm, and shoulder segments - and leg, knee, and foot segments. Also in place now are your baby's kidneys, and they're poised to begin their important work of waste management."
