What is happenning now?
You are now 13 weeks pregnant, which is the beginning of week 14.
Your baby measures about 9 cm in length (3.6 inches) from head to toe and weighs approximately 45 grams (1.56 ounces).
During this week, your baby's body grows more rapidly than their head. Their gag reflex now begins to function, which is important for survival after being born and closely associated with their swallow, cough and sneeze reflexes. Your baby's nose and nasal passages are now fully developed.
Did you know? Until recently, scientists did not think unborn babies could smell because this probably depended on breathing air. However, it is now known that the amniotic fluid surrounding an unborn baby passes through their mouth and nasal cavities, possibly triggering their sense of smell. A newborn baby is naturally drawn to the smell of breast milk after birth, even though they have no previous experience of it. It may be that they are cued for this before birth!
