Pregnancy Week by Week

Get a window on what’s happening in your pregnancy, week by week. From week four to week 42, your baby is experiencing a miraculous transformation from a clump of cells to a fully formed (and totally cute) newborn. Just imagine, as early as five weeks, your baby is already starting to form major organs (heart, stomach, liver, and kidneys) and systems (digestive, circulatory, nervous). By eight weeks, your raspberry-sized womb-mate is moving her arms and legs. At the beginning of your second trimester (week 14), your wee one is sucking his thumb. By week 28, the first week of the third trimester, baby (now as big as an eggplant) is prepping for breathing, developing his eyesight and packing on pounds in anticipation of life outside the womb. Each week is a new miracle. Less miraculous is how a mom-to-be may feel. Pregnancy Week-by-Week charts your baby’s development but also lets mom know what she might be feeling during each week of her pregnancy. Pregnancy week by Week includes everything mom needs to know to feel a sense of control over her pregnancy. Each week offers a complete guide to what you might feel, your must-do’s, your nice-to do’s, and answers and advice on everything pregnancy-related. Plus each week’s guide offers tips on maintaining a healthy and comfortable pregnancy from strategies on coping with pregnancy symptoms (morning sickness anyone?) to ideas for healthy eating, and pointers on talking to your OB. Let us guide you along your pregnancy, week by week.

What are some different birthing positions, and are some better than others?

The Bump Expert

In the movies, it seems like the pregnant woman is always leaning back on an inclined hospital bed with her legs in stirrups, getting ready to push. And that’s most likely the position you’ll find yourself in if you choose an epidural. But for other moms-to-be, there’s definitely more than one way to birth a baby. Some laboring women will try standing, walking, sitting, squatting, getting on all fours or doing whatever else it takes to speed the process along. Know that the birthing position that will work best for you is highly individual -- and you likely won’t stick to just one the whole time you’re pushing.

Each position has its pluses and minuses. Squatting, for example, uses gravity, encourages a quicker descent and requires less effort to bear down, but it’s also hard to stay that way for a long period of time. Getting on your hands and knees can help alleviate back labor and can make delivering a baby who’s “sunny-side” (face) up a little easier, but it can also make it hard to see what’s happening. You can also try sitting or lying facedown over a birth ball or turning onto one side. Feel free to experiment, since you never know what will feel most comfortable while you’re in the thick of it -- and what’s going to help you get the baby out more easily and with less pain.
