19 Weeks

Your baby weighs about 8 1/2 ounces, and he measures 6 inches, head to bottom — about the size of a large heirloom tomato. The hair on his scalp is sprouting. If your baby is a girl, she already has 6 million eggs in her ovaries. This is a crucial time for sensory development: Your baby's brain is designating specialized areas for smell, taste, hearing, vision, and touch. He may be able to hear you as you talk. Research shows that he's learning to distinguish your voice from others, and he'll soon show a preference for it. Let Dad get in on the act, too — encourage him to talk to your baby.
We are getting so excited!
