The baby’s lungs are now secreting a gaseous substance called surfactant, a substance which will help her air sacs inflate as she exits your body. Your baby continues to practice breathing movements. Although what enters her lungs right now is only amniotic fluid, it’s an essential practice to be able to breathe when the time comes.

The development of the brain continues and the reactions to the sounds from the outside are more predictable. She will soon be able to detect the change of light outside due to the fact that her retinas are already practically formed. The eyelids are opening up little by little.

This week your baby weighs about 14 inches and a half or 35 centimeters and weighs almost two pounds or 875 grams.
