Update from BabyCenter.com:
How your baby's growing: Your baby is still putting on the pounds — about an ounce a day. He now weighs almost 6 pounds and is a little less than 19 inches long. He's shedding most of the downy covering of hair that covered his body as well as the vernix caseosa, the creamy substance that covered and protected his skin during its submersion in amniotic fluid. Your baby swallows both of these substances, along with other secretions, which will stay in his 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 he's in a head-down position by now, which is optimal for a smooth delivery, but if he 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 him from the outside of your belly.
** Baby is definitely head down. So that's good news. We saw a meconium poop in the video they showed us Saturday and it's nastier than you can imagine. You have to coat baby's bum with petroleum jelly before he does this poop or it will stick to his skin. It's like tar!
How your life's changing: While your baby continues to grow and crowd your internal organs, you may find that you're not as hungry as you were a few weeks ago. Smaller, more frequent meals are often easier to handle at this point. On the other hand, you may have less heartburn and have an easier time breathing when your baby starts to drop down lower in your pelvis. This dropping — called lightening or engagement — is more likely to happen before labor if this is your first baby. When it does, though, you may feel increased pressure in your lower abdomen, making walking increasingly uncomfortable. Some women say it feels as though they're carrying a bowling ball between their legs, or as if the baby is going to fall out. (Don't worry, she won't!)
** Baby has definitely dropped a bit. My boobs are no longer resting on my belly since my belly is noticeably lower. And yes, it does feel like there's something between my legs - though not as heavy as a bowling ball.
