Our growing baby now measures about 4 inches long, crown to rump, and weighs in at about 2 1/2 ounces (about the size of an apple). She's busy moving amniotic fluid through her nose and upper respiratory tract, which helps the primitive air sacs in her lungs begin to develop. Her legs are growing longer than his arms now, and she can move all of her joints and limbs. Although her eyelids are still fused shut, she can sense light. If you shine a flashlight at your tummy, for instance, she's likely to move away from the beam. There's not much for your baby to taste at this point, but she is forming taste buds. If I were to peek inside my uterus during this week, I would still be able to see our baby's blood vessels through his paper-thin skin. This week, our baby will start producing lanugo, which is fine hair that will cover baby's body up until a few weeks before birth. Our baby now might start sucking his thumb.
Maybe by next week, I'll try to have an ultrasound so that we may be able to find out whether our baby's a boy or a girl! (Don't be too disappointed if it remains a mystery, though. Nailing down your baby's sex depends on the clarity of the picture and on your baby's position. He or she may be modestly curled up or turned in such a way as to "hide the goods.") Hoping for a baby boy this time! *wink*
