As a mother-to-be, you may be wondering when your baby’s lungs will be fully developed. After all, the lungs are vital organs that play a crucial role in breathing and providing oxygen to the body. Understanding the timeline for lung development can help you prepare for your baby’s arrival and ensure that they receive the best possible care.

When Do Lungs Begin to Develop in a Baby?

Lung development begins early in pregnancy, around week 4. At this stage, the lungs are still just small buds that will eventually grow and mature. By week 8, the lung tissue begins to produce a substance known as surfactant, which helps to keep the air sacs in the lungs from collapsing. This is an important step in preparing the lungs for breathing outside of the womb.

When Are Baby’s Lungs Fully Developed?

While lung development varies from baby to baby, most babies’ lungs are fully developed by around week 37 of pregnancy. This is why babies born prematurely, before 37 weeks, often have difficulty breathing and may require assistance with breathing until their lungs are fully developed. In some cases, premature babies may also develop respiratory distress syndrome due to a lack of surfactant in their lungs.
