9 Weeks 2 Days

Online update of the baby this week:

Your baby is nearly an inch long — about the size of a grape — and weighs just a fraction of an ounce. It's starting to look more and more human. It's essential body parts are accounted for, though they'll go through plenty of fine-tuning in the coming months. Other changes abound: Your baby's heart finishes dividing into four chambers, and the valves start to form — as do it's tiny teeth. The embryonic "tail" is completely gone. Your baby's organs, muscles, and nerves are kicking into gear. The external sex organs are there but won't be distinguishable as male or female for another few weeks. It's eyes are fully formed, but the eyelids are fused shut and won't open until 27 weeks. It has tiny earlobes, and her mouth, nose, and nostrils are more distinct. The placenta is developed enough now to take over most of the critical job of producing hormones.
