How big is baby?

Your fetus currently enjoys a 1:1 ratio between body and head, and has skin so transparent that blood vessels show right through. But, fingers and toes are no longer webbed, and hair follicles, tooth buds and nail beds are forming -- setting up a significantly more attractive future.
As soon as your belly starts to curve outward, you'll discover that the world is full of uncertified pregnancy experts. While unsolicited comments can range from amusing ("Eat carrots or your child will be nearsighted") to downright scary ("All that exercise is hurting the baby!"), try not to let them get to you. You and your health-care provider are the best judges of appropriate pregnancy behavior. A polite "Thanks, I'll check with my doctor about that," should end the unsolicited remarks.
