Your baby this week

  • The bones harden and the skeleton shows clearly on a scan.
  • Even with closed eyelids, the baby can sense bright light.
  • Taste buds form and the baby starts to swallow amniotic fluid.
  • The baby moves a lot: turning, kicking and opening and closing its hands.

Your body this week

  • Your nose may feel blocked or you may snore, because the lining of the nose swells.
  • Many women feel better and more energetic in these weeks.
  • You may still have heartburn or constipation.
