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.

23 Weeks Pregnant

At 23 weeks, baby’s really getting ready for her big debut, listening in on what’s going on in the outside world. And you’re getting ready too. Just remember: While having the nursery painted and stocking it with diapers is important, there are some other pressing things you should have on your radar. Namely, financials. Around week 23 is a good time to call your and your partner’s insurance agent to check how you’re currently covered and decide what adjustments you’ll want to make for baby. You might also want to start thinking about writing a will, if you don’t have one, or updating your current one. How’s baby’s savings account going? If you’re like, “what savings account?” that’s okay. But decide whether or not you want to start one for her. One study found that kids who have their own savings account are more likely to go to college, and another one estimated the average cost of raising a baby until age 18 to be over $226,000. Whoa!

your baby's the size of a grapefruit!
At about 10.5 to 11.8 inches and about 12.7 to 20.8 ounces, baby's not just getting bigger, she's getting even cuter.

your baby at 23 weeks
  • She's forming little nipples (yeah, really!)
  • Her face is fully formed now -- she just needs a little extra fat to fill it out.
  • She's listening to your voice and your heartbeat -- and even to loud sounds like cars honking and dogs barking.
