As your baby’s lungs are developing full speed ahead, the sense of smell is also at work! The nostrils and nose have developed quite well at week 25, which allows your baby to practice breathing through these organs!

Before, experts thought that nostrils remain plugged during pregnancy, but modern research now points out that they become open starting this week, and stay this way until the end of the pregnancy.

Since there is technically no air in the womb, your baby is not actually breathing oxygen. Remember that oxygen comes from you and travels through the umbilical cord to your baby, so your little bean receives quite enough. Your baby is simply practicing for the grand exit!

Since your baby’s brain is also quite developed at this point, the sense of smell may now be at work, though of course your baby won’t be able to smell anything yet - except for amniotic fluid, perhaps!
