Changes occur during 16th week of pregnancy

Baby's Development -

  • Baby is sucking her thumb and all her joints and limbs can move.
  • Fine, downy hair called lanugo has started to grow on baby's body, but this will disappear before birth.
  • Her body is growing faster to catch up with the size of her head.
  • The baby now weighs about 3.9 ounces (110 grams) and measures about 4.7 inches (12 cm) in length from crown to rump. 
  • Baby can hold his or her head erect, and the development of facial muscles allows for a variety of expressions, such as squinting and frowning.


Woman's Body -

Between weeks 16 and 18 of pregnancy, health care provider may offer woman a second trimester screening test (known as the multiple marker test or triple screen), which measures the levels of alpha- fetoprotein (AFP), a protein produced by the fetus, and the pregnancy hormones hCG and estriol in the mother's blood. The results of these tests can tell moms whether babies are at risk for (not whether they have) neural tube defects such as spina bifida or chromosomal abnormalities such as Down syndrome. An abnormal result does not necessarily mean that baby has a problem — but it may mean more testing is required. If woman have any emotional or physical worries, there'll be an opportunity to discuss them with doctor.
