When Do Lungs Develop In Babies?

As a new mom, you may be wondering when your baby’s lungs will develop. It’s a common question that many parents have, and it’s important to know the answer so you can ensure your baby’s health and development. In this article, we’ll discuss when lungs develop in babies, what factors affect lung development, and how you can support your baby’s lung development.

When Do Lungs Develop In Babies?

Lungs start to develop in babies as early as the fourth week of pregnancy. However, they are not fully formed until the end of the third trimester, which is around 36 weeks. During the first trimester, the lung buds form, and the trachea and bronchi start to develop. In the second trimester, the lungs continue to develop, and the alveoli, which are the tiny air sacs that enable oxygen exchange, start to form. In the third trimester, the lungs mature, and the baby starts to practice breathing movements in preparation for birth.

It’s important to note that premature babies may not have fully developed lungs, which can lead to respiratory problems. That’s why doctors monitor premature babies closely and may provide oxygen therapy or other treatments to support lung development.
