Pregnancy week 33
  • Baby is the size of a head of lettuce
  • Rapid brain growth affects size of baby’s head
  • Your actions affect baby’s movements

Your baby is the size of a head of lettuce. Bones are continuing to harden; the only ones that will stay soft are inside baby’s skull. This week’s rapid brain growth has increased the size of baby’s head. There will still be soft spots in your baby's skull in the first few years so the brain has room to grow. Fat continues to accumulate and is turning the appearance of the skin from red to pink. Your actions such as how much you eat, when you eat, the position you’re in and sounds from outside the womb, are now affecting baby’s movement and activity level.
