Baby should soon descend into your pelvis, which will give your lungs a little room to breathe (literally). The bad news: This puts the brunt of baby's weight on your hips and pelvis, and will make them pretty sore. Add in your ever-loosening ligaments, and you may soon be taking on that oh-so-adorable pregnancy waddle.
Baby's skin is getting smooth and soft, her gums are rigid, her liver and kidneys are in working order, and her circulation and immune system are basically good to go. Her lungs are the only organs that still need to fully mature, but every day she gets a little closer to breathing on her own.
Your baby is still packing on the pounds — at the rate of about an ounce a day. She now weighs almost 6 pounds (like a crenshaw melon) and is more than 18 1/2 inches long. She's shedding most of the downy covering of hair that covered her body as well as the vernix caseosa, the waxy substance that covered and protected her skin during her nine-month amniotic bath. Your baby swallows both of these substances, along with other secretions, resulting in a blackish mixture, called meconium, will form the contents of her first bowel movement.
At the end of this week, your baby will be considered full-term. (Full-term is 37 to 42 weeks; babies born before 37 weeks are pre-term and those born after 42 are post-term.) Most likely she's in a head-down position. But if she isn't, your practitioner 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 by manipulating her from the outside of your belly.
And a more personal 36 week milestone, as of today, my Drs will not stop it if I go into labor on my own.
