Though you can't see them yet, your little one is busy practicing facial expressions this week! Your fetus owes this new ability to smile, frown, and squint to facial muscles that have recently developed. And that expressive face is housed in a head that can be held fairly erect by week 16. Meanwhile, your baby's heart is busy pumping, moving about 25 quarts of blood each and every day. Your baby is now about 4 inches long, and weighs 3 ounces. In other words, about the size of an avocado! This development means that your fetus's legs are now almost proportionate to that growing body. In fact, all this growing may mean you'll soon be able to feel a quickening; the faint first movements of your baby! But if your abdomen remains movement-free, don't worry-some women don't feel their baby's first fluttery kicks until week 20. Want to know more? Check back right here for your next video update.More »

Thank goodness! Your baby is settling in and getting down to the serious business of growing, so you're probably much more comfortable than you were during the first few months of your pregnancy. Now that you've reached week thirteen (and beyond), your baby will begin to grow at his or her own pace, although all fetuses do follow a similar pattern. During your fourth month, your baby will grow to be up to four and a half inches in length...that's the size of a large orange! Eyebrows, eyelashes, and even some hair...by now, your baby has them all! And it's not limited to your little one's head: Babies in the womb are covered with a downy layer of hair called lanugo, which is mostly for warmth and is usually shed before birth. And maybe it's time to start singing in the shower...your baby's ears have moved from the back of his or her neck to the sides of the head and, because tiny ear bones are now in place, he or she may be able to hear you! Your little one is also developing vocal chords, and his or her backbone and neck are becoming more erect. So, aside from growing, what does your baby do all day? The answer is simple...Practice! He or she will spend the day rehearsing movements, sucking and swallowing...skills that are vital to survival once that baby is ready to leave your womb.While all these changes take place in your baby, you'll probably notice few changes in your body...a break at last! At this time, most women do begin to experience vaginal discharge, which is known as leukorrhea. This milky, odorless or mild-smelling liquid is normal and helps to protect the birth canal from infection. If the discharge is significant, or if it makes you uncomfortable, you can use a panty liner to absorb it...remember NOT to use a tampon! Some mild side-effects you may experience this month include sensitivity or bleeding in your teeth and gums and congestion in your nasal passages. Both of these side effects are due to those pregnancy hormones and should be cared for gently: With a humidifier for the stuffiness and good oral hygiene for your gums. As your uterus grows, its supporting ligaments stretch to accommodate the weight. This can manifest as achy discomfort on one or both sides of your lower abdomen. Rest in a comfortable position when you experience these round ligament pains...relief usually comes fairly quickly. By the end of this month, your little baby is 16 weeks old...and getting less little by the day! Hopefully, you're experiencing a break in symptoms and enjoying the view as your belly expands!More »

Your little one is now probably able to put that teeny thumb in his or her mouth this week! Although those sucking muscles won't be quite up to the task of doing much with that thumb, your little one will likely take comfort in just having that thumb in his or her mouth. This week, your baby is about three inches long, the size of a clementine. And with this growth, your fetus's large head is finally becoming more proportionate to the size of the rest of the body, Although you still won't know the sex of your child, if you're having a girl, her ovaries will now be home to more than two million eggs! In other news, your baby's most distinctive characteristic-fingerprints-have fully formed on the fingers and toes. Want know what's up with your 14-week-old fetus?

Your fetus shed that fish-like tail a few weeks ago, but now begins to sprout a coating of downy fur! This ultra fine layer of hair, which is called lanugo, will continue to grow throughout the rest of your pregnancy, until it is shed shortly before birth. Meanwhile, your baby's body is growing significantly faster than the head at this point, which sits atop a more prominent neck. This week, that ever growing fetus is about the size of a peach, or 3 1/2 inches long and now weighs about 1 ounces. By now, your baby's arms are proportionate to the body, although the legs still have some growing to do. And while you still can't see them just yet, your baby's genitals have fully formed by this week. In addition, the liver has started to produce bile and the thyroid gland will begin to make thyroid hormones that will regulate metabolism. Wonder what else your little one has in store?
