Pregnancy is an exciting time for expectant parents, as they wait for their little one to make their grand entrance into the world. However, the journey of a baby’s development actually begins in the womb. In this article, we’ll explore the different stages of fetal development, and what parents can expect during each trimester.

First Trimester

During the first trimester, the fertilized egg grows and develops rapidly. By the end of the third week, the baby’s neural tube, which will eventually become their brain and spinal cord, begins to form. By week six, the baby’s heart begins to beat, and their arms and legs start to grow. At this point, the baby is only about the size of a pea, but they already have all of their major organs.

Second Trimester

The second trimester is often referred to as the “golden period” of pregnancy, as many women begin to feel better and more energetic. During this time, the baby continues to grow and develop at a rapid pace. By week 20, the baby can hear sounds from the outside world, and they may even begin to recognize their parents’ voices. Around this time, the baby also begins to develop their sense of touch, as they start to explore their surroundings in the womb.

Third Trimester

During the third trimester, the baby’s growth rate begins to slow down as they prepare for birth. The baby’s brain continues to develop rapidly, and they begin to practice breathing by inhaling and exhaling amniotic fluid. By week 36, the baby is considered “full-term,” meaning they are ready to be born. However, many babies are born between 37 and 42 weeks of pregnancy.

Frequently Asked Questions

1. How does a baby get oxygen in the womb?

Throughout pregnancy, the baby gets oxygen from the mother’s bloodstream via the placenta, which is a temporary organ that connects the baby to the mother’s uterus. The placenta also helps to remove waste products from the baby’s blood.

2. Can babies feel or sense anything in the womb?

Yes, babies can feel and sense things in the womb. By the second trimester, the baby’s nervous system is developed enough for them to feel touch and respond to stimuli, such as sound and light.

3. What happens if a baby is born prematurely?

If a baby is born prematurely, meaning before 37 weeks of pregnancy, they may have health problems, such as difficulty breathing, feeding, and regulating their body temperature. However, with proper medical care, many premature babies go on to live healthy lives.

4. Can a mother’s stress affect the baby in the womb?

Yes, a mother’s stress can affect the baby in the womb. Studies have shown that high levels of stress hormones, such as cortisol, can cross the placenta and affect the baby’s development, including their brain function and behavior.

5. When can a baby recognize their parents’ faces?

Babies can recognize their parents’ faces within hours of birth. However, it’s not until around six months of age that babies begin to show a preference for familiar faces, such as their parents’.


In conclusion, a baby’s development in the womb is a remarkable process that takes place over the course of nine months. From the formation of their organs to their ability to hear and sense their surroundings, each trimester brings new milestones and experiences for both the baby and the expectant parents. By understanding the different stages of fetal development, parents can better prepare for their baby’s arrival and appreciate the miracle of life.
