our baby: 19 weeks

Your baby weighs about 8 1/2 ounces, and she measures 6 inches, head to bottom — about the size of a large heirloom tomato. Her arms and legs are in the right proportions to each other and the rest of her body now. Her kidneys continue to make urine, and the hair on her scalp is sprouting. This is a crucial time for sensory development: Your baby's brain is designating specialized areas for smell, taste, hearing, vision, and touch. If your baby is a girl, she has an astonishing 6 million eggs in her ovaries. They'll dwindle to fewer than two million by the time she's born.
