How your baby's growing: Your baby is still putting on the pounds — about an ounce a day. She now weighs almost 6 pounds and is a little less than 19 inches long. She's shedding most of the downy covering of hair that covered her body as well as the vernix caseosa, the creamy substance that covered and protected her skin during its submersion in amniotic fluid. Your baby swallows both of these substances, along with other secretions, which will stay in her bowels until birth. This blackish mixture, called meconium, will become her first bowel movement.At the end of this week, your baby will be considered full-term. (Babies between 37 and 42 weeks are considered full-term; a baby born before 37 weeks is pre-term and after 42 is post-term.) Most likely she's in a head-down position by now, which is optimal for a smooth delivery, but if she isn't in the next week, your provider may suggest scheduling an "external cephalic version," which is a fancy way of saying she'll try to coax your baby into a head-down position manually, by manipulating her from the outside of your belly.
