Week Thirty One: Baby detects light

  
You are 31 weeks pregnant. (fetal age 29 weeks)
  • Baby weighs 3.5 pounds and measures 16.5 inches from the head to heel.
  • Baby's weight is about 1.6 kg and length around 42cm.
  • The eyes have now completely opened and are responding to light and darkness.
  • A loud noise near you may cause your little one to jump.
31 weeksYour baby continues to grow. Baby's lungs and digestive tract are very near to being mature. Now that almost all of the major organs are functioning, growth will focus on maturing those organs and growing muscle mass and fat stores. Baby's weight gain will exceed its growth in length from now on. He or she should more than double their weight again between now and birth. It weighs about 3.5 pounds (1.6kg), and crown to rump length is 11 inches (28cm). Its total length is 16.5 inches (42cm).

A loud noise near you may cause your little one to jump. Baby may move to the rhythm of music. Studies with heart rates show that they may also prefer some types of music to others at this stage. The eyes can now completely open and the irises are now responsive to light, dilating and contracting as needed.

You will probably find that though you have been feeling pretty energetic throughout your second trimester, you are beginning to slow down now. Pay attention to your body's signals and rest when you need to. Exercise is still an important activity for you, even though it gets harder as you get larger and heavier. Try swimming, stretching and walking all excellent options for pregnant women.

Your total pregnancy weight gain by this time should be between 21 and 28 pounds (9.5 and 12.5kg).
