Perkembangan Bayi : Trimester 3

sambungan ENTRI INI dan INI...

WEEK 27 : I'm a survivor, I'm gonna make it!

fetus in seventh monthYour not-so-tiny-anymore brilliant baby(about 2 pounds and 14.5 inches long!) is slowly rotating in preparation to “head out.” Obviously, this doesn’t happen overnight, but when you start to feel an unfamiliar pressure on your cervix, you’ll know you’ve got a fully flipped baby locked and loaded for the countdown to their birthday! Even now, at the beginning of the third trimester, their little lungs are already capable of breathing air while the pulmonary vascular system can provide sufficient gas exchange and the central nervous system can generally regulate rhythmic breathing as well as their basal body temperature. For what it’s worth, at this point in a healthy pregnancy a premature child (with intensive care) could easily win on the show: “Survivor: The Early Years.”

WEEK 28 : Why, you look positively bovine!

fetus in seventh monthYou know how you’ve been feeling a bit like a barn with legs? Well, that feeling won’t subside before… well, you know, when you finally give birth. For the time being, you’ve got yourself a baby in the business of collecting fat and lots of it! In spite of the dubious joys of being a human-barn, this baby fat business is very serious and you’ve got to put up with it because it’s going to keep your little porker warm and healthy after birth. Other good stuff from inside: their eyes are doing lots of blinking this week because they’re now able to respond to light and dark. Also, their industrious little bone marrow is now a major construction site for developing red blood cells, while their super-cute adrenal glands are actually producing androgen and estrogen—which will stimulate your hormones to begin milk production. Can you say, “Moo?”

WEEK 29 : To pee or not to pee...

fetus in seventh monthIf you’ve been feeling butterflies moving around in your belly, it’s not just your run-of-the-mill pre-birth performance anxiety. No, it’s your amazing baby with a case of the hiccups: a fairly common occurrence at this point resulting from practicing breathing for their big birthday. In addition, to getting a round of butterfly-like hiccups, your little swimmer has arduously managed to accumulate enough baby fat to account for nearly 3.5% of their overall body weight. Yeah, compared to we adults, it’s not a lot, but when they’re little like that—it’s certainly a healthy (and warming) accomplishment in its way. Another fantastic accomplishment: your baby's spleen is now in charge of hematopoiesis—the 10 dollar name for the process involved in building up certain important blood components. Another fantastic-accomplishment: your little monkey has been peeing into their amniotic sac for a little while now (this is why potty training takes a while) and if you didn’t know, actually swallows it along with the rest of the amniotic fluid. Although the concept is nasty, their urine is sterile and as part of the amniotic fluid base, is replaced several times throughout the day. So if you didn’t know before, now you can tell people, that yes, you drank your own urine—you were still in the womb, but nonetheless, you’ve been there.

WEEK 30 : Goodbye monkey baby, hello roly poly!

fetus in seventh monthThe light is visible at the end of the tunnel! Your oversized self and amazing growing baby have finally reached the single digits (in terms of weeks till birth)! The fine lanugo hair that has been growing all over their little monkey-like body is going to start falling off this week in preparation for the big day. But don’t be shocked if they’re hairier than you’d anticipated, some babies keep their lanugo until after birth. Still, it’s not any cause to be concerned as it will fall off eventually. No surprises here: your little porker is getting even cuter with increasingly pudgy arms and legs this week thanks to the ever-growing layers of subcutaneous fat. In terms of numbers, your baby should be weighing in at around 3 pounds 12 ounces (or more!) and be nearly 16 inches long.

WEEK 31 : Another day... another ounce

fetus in seventh monthYour not-so-little-one is just a bit closer to their birth weight and height at around 4 pounds and 17 inches. With each added layer of baby fat, your baby's skin starts to look more and more like it will when they finally get to see the light of day. The heavy news: you can expect your miracle-gro muffin to gain about a half a pound of weight per week from now until about two weeks before birth. Great. That's just what you needed. Even more weight to carry around!

Your baby's still-developing immune system has gained substantial strength over the past few weeks getting them in full gear to face our disease-ridden world o’ wonders. Obviously, a large majority of your child’s immune strength will be derived from exposure to breast milk as well as the outside elements. Their cute little noggin’ (which could already be covered with luscious locks or just purty peach fuzz), is still soft because the skull bones have not yet fused together. As much as that sounds a little too vulnerable, their “skull softness” allows for a much smoother passage through the birth canal during labor—something both you and your little swimmer will appreciate when it’s finally time to “go!” Also, some babies will have that “soft spot” on their head for up to one year after birth.

WEEK 32 : Mommy, you're HOT!

fetus in eighth monthIn the latest womb reports, your amazing baby has now developed sensitivity to temperature! This means you’ll probably get a swift kick if you put a hot pad on your ginormous belly. For the Elton John lovers out there-- yes, baby’s got blue eyes. At this point, all babies do, although depending on their chromosomal disposition, this could easily change after birth (or even between now and labor), but for the time being, blue it is. Thanks to their recently matured lungs and a remarkably strong immune system, over 90% of babies born in their 32nd week, survive premature births. So it’s pretty much a done deal. Even if your little monkey’s planning on heading out early, their survival odds are in everyone’s favor. Time to celebrate (no, no, wait until after the birth to crack open the champagne!) We’re talking baby-showers and alcohol-free punch!

WEEK 33 : Is it just me or is getting a little cramped in here?

fetus in eighth monthFor all the weight and bulk you’re lugging around these days, you’d think your little champ should weigh much more than a mere 5 lbs and measly 17 inches in height, but nope, that’s about the average size for a baby in its thirty-third week. In terms of appearances, they’re getting cuter and pudgier every minute as they pile on the baby fat for those adorable little wrist rolls and chubby toes. And as we’re sure you’ve already noticed they’re getting stronger with every passing day. Nowadays, it’s possible to observe a well-placed kick just by watching your belly—but you already knew that didn’t you? Although they’re getting stronger, your bigger-by-the-day baby is losing space to move around, so the actual rate of movement will drop off in the last few weeks, despite that powerful drop-kick they’ve been working on. Hey, did you know you’ll continue feeling their movements even during labor?

WEEK 34 : Upside-down baby!

fetus in eighth monthYour amazing baby is on the move! They’ve been riding fairly high in your stretched-out womb till now (while kindly compressing your poor internal organs), but now they’re planning on making the big move to your pelvis this week. If you haven’t noticed it already, you’ll be feeling the weight shift that signals that your baby is most likely out of breech position, with their head now resting on your pubic bone. In liver news: although not quite fully formed, your little miracle’s liver is now capable of processing a certain amount of waste. In general, most of your child’s prenatal physical development is pretty much up to snuff and ready for the outside world. Naturally, further weight gain is expected—so you’re still not at maximum capacity despite probably feeling like you definitely are maxed out.

WEEK 35 : Hey! It IS getting cramped in here.

fetus in eighth monthCongratulations! You’re now carrying nearly 6 lbs of baby not counting their amniotic fluid, the umbilical cord, or the placenta itself. We’re impressed because that’s a LOT of work non-stop. Are you feeling proud of yourself yet? Well, get to it—you’ve done an amazing job! At this point, your little grower is almost busting out of the womb size-wise, which make their restricted attempts to move much challenging. Of course, your stubborn little sucker is still trying to move around as if they weren’t in a cramped space. And the accumulationg baby fat deposits are starting to level off so your little butter ball will be padded and warm when they head out of their super snug little home.

WEEK 36 : Wee fingers o' steel

fetus in ninth monthThe countdown continues… and in fetal developments: most of the bones (soft skull aside) in their little body are now completely hardened, providing a solid structure from which they can now make their grand debut into the world. Yes, ladies and gentlemen, we are structurally ready for a secure launch. In physical fitness news: their muscle tone has also improved over these past few weeks, and you’ll definitely be impressed by their steel-like Ulnar grasp (a newborn reflex that occurs if you lay your finger in their palm). And in genital development: if you’re having a girl, her labia are now fully developed. Finally, in the fluids/excretion department: the amniotic fluid-to-baby ratio has fallen over these past weeks, although they’re still swallowing fluid (building up even more meconium for that historic first poop), and some vernix caseosa. They will be more than ready to swallow and digest milk after birth. Just in case you didn’t get it quite yet: you’ve got yourself an adorable and hungry 6.5 lbs 20 inch baby—are you ready?

WEEK 37 : And we're ready for take off!

fetus in ninth monthIt’s the calm before the storm. Changes in your baby's weight have leveled off with only a few ounces of fat added this week. At this point your baby should weigh in at around 7 lbs and 20 inches (with boys somewhat heavier and longer than girls). Happily, as far as internal organs go, they are now developed enough to function in the outside world although the oh-so-important immune system is still developing and will continue to do so after birth. With a large boost of antibodies provided by breast milk when nursing begins. Fighting infection and staying healthy should be well within their physical capacity when your little fighter is born.

WEEK 38 : Stuck in a holding pattern

fetus in ninth monthAs you know, you've arrived at the final leg of your pregnancy journey, and if you're still carrying your little love around, they've just about reached their birth weight (somewhere between 6 to 8 pounds is average depending on whether they're a boy or girl). There really isn't a lot to report on baby this week, so lets do a quick recount of where we're at: all internal organ systems are pretty much ready for the outside world, they've got their meconium stockpile building up (their first black baby poo), lots of healthy baby fat, a rapidly developing brain (that'll keep growing with them for years to come), and they've more or less reached official baby status-- all they need to do is "head out" and say hello to the rest of the world and especially their ready-to-pop momma.

WEEK 39 : The waiting game...

fetus in ninth monthWhether you give birth tomorrow or next week, it's pretty much all the same for your baby, who is now truly R-E-A-D-Y to face the big bright world outside of your womb. Speaking of wombs, your body is priming up for the big moment and hopefully, you're as prepared mentally as you can be. Your baby is well stocked up on fat, all their organs have put on the finishing touches. Here's hoping your child is already in the birthing position and basically just "hanging out" waiting for that elusive moment when all systems synchronize in your body to trigger the labor process.

WEEK 40 : Three, two, one... BLAST OFF?!

fetus in ninth monthThis is it. If you haven’t already gone into delivery, we’ve officially arrived at that time where all you’re doing is trying to patiently play the oh-so-maddening waiting game. Your long-awaited miracle is undoubtedly just as impatient as you to get things moving along. You can generally expect a head-first delivery unless your healthcare provider is unable to coax them out of breech position, in which case their feet come first. After nine months of waiting and even after your wonder-baby is finally out, your doctor or midwife will probably make you wait another five minutes while they give your child an Apgar score (see below); suction any fluids or mucous that may be blocking their newly exposed airways; and clean the remaining vernix and blood from their little body. After all the waiting, you’ll finally get to hold your exhausted little love-bug. Just a heads up: it’s fairly common for newborns to have a bit of chapping or even red rashes on their skin. Gerber babies don’t just pop out sparkly clean and smooth from the womb.

It’ll come whether you’re ready or not, so grab your bag, call the doc, get a hold of the grandfolks-to-be and get ready to execute your much-rehearsed plan of action. PLEASE DO NOT put the pedal to the metal. Labor typically last 13 hours (8 hours for mothers who have delivered once already), and getting to the birth center 10 minutes earlier isn’t likely to make a big difference. Try to keep a level head and drive safely: there’s a lot at stake.
