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.

And how's mom doing?
Have you felt anything you suspect might be contractions already? Braxton-Hick contractions are part and parcel of the second half of pregnancy and lucky for you, become more frequent during the third trimester. Cleverly dubbed "false labor" contractions, these spasms are an obnoxious fake-out and shouldn't be confused with premature labor. The fun part of having BH contractions is that it's not unusual for them to be painful... and by fun, we mean "why oh why, does the third trimester mean everything is uncomfortable?" Still, just a heads up: if you notice the contractions more than four times in one hour, or even more glamorous—changes in your vaginal discharge, call your healthcare practitioner right away.

As for other third-trimester niceties; your nipples may be engaging in a bit of "pre-milk" expulsion at the most untimely moments. So next time you've got yourself a pair of damp head-lights in the grocery store, just go ahead and purchase the nursing pads to protect your clothes, bras, and any remaining shreds of dignity you can salvage.

As your magical growing baby obstinately refuses to shrink or give back any real-estate in your belly, you can sit back, "relax," and take in the heartburn and increased lower back pain. If you choose, you can always eat less with each meal, and instead opt for smaller more frequent meals, this should help the heartburn. As for your poor back, get off your feet and elevate them above your heart, double-check the names list, and how many key baby-items you've already got in your registry. If you're lucky, you might just make it in less than eight weeks! Hang in there wonder-mom, we believe in you!

As for the ongoing joys of being in your third trimester: your not-so-fun symptoms are just intensifying this week, so it might not hurt to slow down a bit and focus on yourself. If you're feeling extra fatigued, you've probably joined the sleeping shouldn't be this tough when I'm this tired club, especially if you're experiencing a lot of back pain and general discomfort. If you've been pushing the exercise thing, then this is the time perhaps to cut down on the physical activities and focus more on getting proper sleep (if this means buying a pregnancy pillow, then do it!). Oh and all that moodiness? Just go with the flow emotionally. This doesn't mean letting the hormones win and becoming a complete psychotic. Instead, feel the feelings, but know that the drama you're feeling is largely a result of increased adrenaline thanks indirectly to hormonal swings—not because things really are that dramatic and merit adult temper tantrums. The clincher symptom for this week: it's highly likely your libido has gone on sabbatical. This, as far as we're concerned, is perfectly natural in your condition.

Now, if you are planning or deciding whether or not to breastfeed, here are some of the big reasons why it's a great thing for you and your little "sucker": breastfeeding actually releases a hormone that will help you relax (and if you don't nurse milk production will actually cease: i.e. use it or lose it!). If you choose to breastfeed, your body will produce oxytocin—(no, not Oxycotin, Rush Limbaugh already took care of that), which actually increases uterine contractions to decrease post-birth vaginal bleeding.

And the vain reason to breastfeed: all that charming excess body fat you've gained is used for milk production, thus making it MUCH easier for you to return to you pre-pregnancy weight. Also, nursing mothers' bones re-mineralize faster than those who don't and are less likely to contract ovarian or uterine cancer before and after menopause. Not to mention the fact that breastfeeding means you're directly bolstering your baby's immune system. For even more reasons why your child will benefit from breastfeeding, visit womenshealth.gov.

As if we have to tell you: their little "cute" kicks are getting stronger these days, but just pay attention. If you notice a significant drop in the number of kicks experienced per hour it would be a good idea to tell your physician or mid-wife. But before you start getting anxious, keep in mind that during the final weeks of pregnancy your in-house-football player will be kicking significantly less as they will lack the space to move about as vigorously.

Yes, ladies, you've finally reached the infamous "live-on-the-toilet" stage. Your feet are bigger, your breasts are bigger, your belly is bigger, even your baby is bigger—and something's gotta give. Annoyingly, nature didn't choose your butt and instead opted to compress your bladder, which is now being completely squashed by your-super-sized-baby... all day long. So your best shot is to just accept the fact you're going to need to urinate every 10 minutes (and if you manage to go longer, thank the good lord).

Of course breast tenderness is also very common at this phase as milk production is kicking in. Other thrilling third-trimester symptoms include more swelling (known as edema) and feeling like you live in a sweat factory as a result of increased basal body temperature. Thank your baby: this temperature increase stems from their body heat coupling with your own, which of course all adds up to one hot mama!

Just in case you don't have enough things to stress out about: we'd like to remind you the third trimester is really a time to kick your baby-on-the-outside preparations into high gear: baby-proof the home or apartment, buy a car-seat, get a stroller, dress up the nursery and plan a space for diapering, keep mulling over possible names, and try to enjoy this time… when you're not nauseous, constipated, running to the toilet, or just plain wiped out. (And don't forget to get your sleep, be active, and eat well! Phewee! we're tired just thinking about what you're going through!)
