At 28 weeks, a fetus is about the size of an eggplant, measuring around 14.8 inches and weighing about 2.2 pounds.
Physical Development at 28 Weeks
At 28 weeks, significant physical changes are occurring in the fetus. This stage marks the beginning of the third trimester, a crucial period for growth and development. The fetus is now approximately the size of an eggplant, measuring around 14.8 inches (37.6 cm) in length and weighing about 2.2 pounds (1 kg). This growth spurt is vital as the fetus prepares for life outside the womb.
The skin of the fetus is still quite thin but is beginning to develop a layer of fat underneath, which helps with temperature regulation after birth. The skin may appear wrinkled due to its thinness, but this will change as more fat accumulates over time. At this stage, the fetus also starts to develop more distinct facial features, including eyelids that can open and close, and eyebrows that begin to form.
Body Proportions and Features
Around this time, the body proportions of the fetus are becoming more recognizable. The head is still relatively large compared to the rest of the body but is starting to become more proportional as growth continues. The limbs are more developed and can be seen moving in ultrasound images.
The fingers and toes are fully formed with tiny fingernails and toenails beginning to grow. The hair on the head may also start to become visible, although it can be fine and sparse at this stage. The overall appearance becomes more human-like as soft tissues continue to fill out.
Internal Development at 28 Weeks
While physical appearance changes are evident, internal developments are equally significant during this week. The brain is rapidly developing, with neurons forming connections that will be crucial for future cognitive functions. By this point in pregnancy, brain activity can be detected through various imaging techniques.
The lungs are maturing as well; they begin producing surfactant—a substance that helps keep air sacs from collapsing after birth. This development is critical for breathing once the baby arrives in the world.
Organ Functionality
The kidneys are functioning efficiently by now, producing urine that contributes to amniotic fluid levels. This fluid plays an essential role in cushioning the fetus and allowing for movement within the womb.
Additionally, the heart rate typically ranges from 120 to 160 beats per minute at this stage, which can often be detected during prenatal check-ups using a Doppler device or ultrasound.
| Development Aspect | Description |
|---|---|
| Size | Approximately 14.8 inches long and weighs about 2.2 pounds. |
| Skin | Thin skin developing a layer of fat underneath. |
| Brain Development | Rapid neuron formation; basic brain activity detectable. |
| Lungs | Maturing with surfactant production for breathing. |
| Kidneys | Fully functional; producing urine contributing to amniotic fluid. |
Sensory Development at 28 Weeks
By this point in pregnancy, sensory development has progressed significantly. The eyes can now open and close, allowing for light perception even though they remain closed most of the time due to their position in the womb.
Hearing is another critical aspect of sensory development during this stage. Fetuses can hear external sounds—such as voices or music—and may respond by moving or increasing their heart rate when they hear familiar sounds.
Taste buds are also forming; studies suggest that flavors from maternal diet can influence fetal taste preferences later on after birth.
The Role of Amniotic Fluid
Amniotic fluid plays several vital roles in fetal development at this stage. It provides cushioning against external pressure or trauma while allowing room for movement and growth. Additionally, it helps regulate temperature within the womb.
As previously mentioned, fetal urine contributes to amniotic fluid levels; therefore, maintaining adequate hydration during pregnancy is essential for ensuring optimal fluid levels.
The Mother’s Experience at 28 Weeks
As exciting as fetal development is at this stage, mothers may experience various physical changes as well during week 28 of pregnancy. Common symptoms include increased fatigue due to weight gain and hormonal fluctuations.
Mothers may notice changes in their sleep patterns; finding comfortable sleeping positions becomes challenging as their bellies grow larger. Additionally, Braxton Hicks contractions—irregular practice contractions—may begin occurring as the body prepares for labor.
It’s crucial for expectant mothers to stay active while listening to their bodies’ needs during this period. Regular prenatal check-ups ensure both mother and baby remain healthy throughout pregnancy.
Nutritional Needs During This Stage
Proper nutrition becomes even more vital during these final weeks leading up to delivery. A balanced diet rich in essential nutrients supports both maternal health and fetal growth:
- Protein: Important for tissue repair and growth.
- Calcium: Supports fetal bone development.
- Iron: Essential for preventing anemia.
- Folic Acid: Crucial for neural tube development.
- Hydration: Helps maintain amniotic fluid levels.
Expectant mothers should consult healthcare providers regarding any dietary restrictions or supplements needed during pregnancy.
Ultrasound Imaging at 28 Weeks
Ultrasound imaging serves as an invaluable tool during pregnancy by providing insights into fetal health and development while allowing parents-to-be a glimpse of their baby before birth.
During a typical ultrasound around week 28, healthcare providers assess various aspects such as:
- Fetal size
- Heart rate
- Position within the womb
- Amniotic fluid levels
These assessments help ensure that everything is progressing smoothly toward delivery day.
The Emotional Journey During Pregnancy
Expecting parents often experience a whirlwind of emotions throughout pregnancy—anticipation mixed with anxiety about what lies ahead once their baby arrives home from the hospital.
Bonding with your unborn child through activities such as talking or playing music can enhance emotional connections even before birth occurs! Engaging partners in these experiences fosters shared excitement while preparing them both mentally for parenthood together.

Frequently Asked Questions
What does a fetus look like at 28 weeks?
At 28 weeks, a fetus resembles an eggplant, measuring about 14.8 inches and weighing approximately 2.2 pounds. Its skin is thin and wrinkled but begins to develop a layer of fat, improving temperature regulation for life outside the womb.
What physical changes occur in a fetus at 28 weeks?
Significant physical changes happen at this stage, including more recognizable body proportions. The head becomes more proportional to the body, and limbs are well-developed with fully formed fingers and toes. Distinct facial features like eyelids and eyebrows also start to become visible.
How does the internal development of a fetus progress at 28 weeks?
Internally, the fetus experiences rapid brain development with neurons forming crucial connections. The lungs mature as they begin producing surfactant, essential for breathing after birth. These developments are vital as they prepare the fetus for life outside the womb.
What can be observed during an ultrasound of a 28-week fetus?
During an ultrasound at 28 weeks, you can see distinct movements of the limbs and better-defined facial features. The head is larger in proportion to the body, and fine hair may be visible on the scalp. These images provide insight into the fetus’s growth and development.
How does a fetus’s heart function at 28 weeks?
At this stage, a fetus’s heart rate typically ranges from 120 to 160 beats per minute. This heartbeat can often be detected during prenatal check-ups and is an important indicator of fetal health and development as pregnancy progresses.
