One of the most exciting moments for a parent-to-be is hearing their baby’s heartbeat for the first time. But when does a baby actually develop its heart? In this article, we’ll explore the stages of heart development in a growing fetus.

Week 3: The Beginning of Heart Development

Believe it or not, a baby’s heart starts to develop just 3 weeks after conception. At this point, the embryo is only about the size of a grain of rice, but it already has a tiny tube-like structure that will eventually become the heart.

Weeks 4-7: Formation of the Heart Chambers

Over the next few weeks, the tube-like structure begins to bend and fold, forming the four chambers of the heart. The heart begins to beat on its own around week 5 or 6, but it’s still too early for a pregnant woman to hear the heartbeat.

Weeks 8-9: The Heart Takes Shape

By week 8 or 9, the heart begins to take on its characteristic shape, with the four chambers and major blood vessels in place. At this point, the heartbeat can usually be detected by a doctor or midwife using a fetal Doppler device.
