  • The fetus is covered with a protective soft down to regulate its temperature.
  • Fat begins to form underneath skin.
  • Baby hears external voices, sleeps and dreams.
16 weeksYour baby has learned to breathe. This is apparent from the regular movements of his chest, inhaling and exhaling small amounts of amniotic fluid. These actions help the lungs to develop and grow. More developed facial muscles may lead to various expressions, such as squinting and frowning. Your baby nows weighs more than their afterbirth. The baby can grasp with his hands, kick, or even somersault.

You are showing more now and have an obvious swelling in your lower abdomen. The rest of your body is still changing. A total of 5 to 10 pound (2.25 to 4.5 kg) weight gain by this point in your pregnancy is normal.

The crown to rump length of your baby is 4.4 to 4.8 inches (11 to 12 cm). Fetal weight has doubled in 2 weeks and is about 3.5 ounces (100g).
