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.

Fetal Hearing -- Is Loud Noise Safe During Pregnancy?

The Bump Expert

Those tiny inner ears have been forming since month four, but by month six they’re becoming well developed. Go ahead and sing, chat, read and play your favorite tunes for your mini-me. Studies show that, while lots of sounds are filtered out by the uterine wall and amniotic fluid, baby is able to hear, respond to, and remember sounds from his time in the womb. It’s the lower-frequency noises that make it through, so go heavy on the bass. As for volume, you should be fine taking in a concert or sitting by a horde of screaming football fans -- just be ready for baby to react to all the hoopla, especially during the last trimester. The jury’s still out on whether frequent loud noises are truly safe. If you work in an especially noisy place (we're talking about loud machinery here; not your annoying cube-mates), talk with your OB about making a new plan.
