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.

Q&A: What screening tests are given to newborns?

What screening tests do hospitals generally give newborns?

Re: What screening tests do hospitals generally give newborns?

The Bump Expert

Medical staff usually performs a few tests to screen baby for potentially harmful or life-threatening (but mostly very rare) diseases before he heads home from the hospital, 24-48 hours after birth. This generally involves simply pricking baby’s heel to draw a few drops of blood, and testing his hearing with a tiny earphone. Every state requires screening for at least 29 conditions, but baby could wind up being tested for up to 31 metabolic disorders, ranging from hypothyroidism to maple syrup urine disease (seriously). Differences vary by state depending on funding, laws, financial costs and availability of tests and treatments.

To find out which tests your state requires, head to the National Newborn Screening and Genetic Resource Center. Many of these tests can be run from that same sample of blood, so talk to your doctor about your family history and any tests that your state doesn’t routinely offer. Chat about the pros and cons of screening for certain disorders. Early intervention can make all the difference with some of these diseases -- detecting disorders early can save your baby’s life or help him avoid mental retardation.

Also, if you and baby are lucky enough to head for home after 24 hours or less, you may need to head back to the pediatrician within the next week or two for testing. (Many of these screenings need to be performed after the first 24 hours of life.) Above all, don’t stress about these routine tests -- the disorders they screen for are rare, and if one does come back positive, there'll be plenty of time to think about it then.
