How big is baby?

Your baby is now the size of a cauliflower. At this point, he may be able to distinguish between your voice and your husband's or partner's voice.

Baby's Development

Your baby has been hiccuping every once in a while for several weeks, and now you might actually feel these baby hiccups, which are triggered by the involuntary movements of his diaphragm. (In adults, this is followed by the quick closure of our vocal cords, which is what makes that familiar "hic" sound.) But because your baby's trachea is filled with fluid instead of air, his fetal hiccups don't make a sound. They will make your belly jump though, which is fun to see and feel!

Week 27 Ultrasound

Now that the baby-to-be is growing rapidly, it's harder to get a complete profile in the womb (she just doesn't fit in the picture anymore!). Even though she has more than tripled her weight since this trimester began, there's still plenty of growing left to do. This week marks the end of the 2nd trimester -- just one more trimester to go.

Mom's changing body

Are you usually one of those shy, don't-rock-the-boat types? Many women find that being pregnant makes them more assertive than usual -- and better equipped to set boundaries at home, at work, or anywhere. The awareness that you're responsible for another little person is often motivation enough to speak up or say no when necessary -- say, asking a friend (or a stranger) to stamp out her cigarette when she's lighting up nearby. Pregnancy also has a way of making you hyper-attuned to your instincts. So that tiny voice in the back of your head telling you "I need a seat on this overcrowded bus -- stat!" is suddenly toting a megaphone, which helps you go with your gut and do what's best for you and your baby. And the more you can get in the habit of setting limits now, the happier and less frazzled you'll be once you're no longer a party of two.

Weekly Tip

If your ever-growing bump is starting to get in the way of your fitness routine, take your workout to the pool. A big belly can make jogging or aerobics uncomfortable, but swimming will likely feel soothing as you move weightlessly through the water.
