Pregnancy: Week 30

The 30th week of pregnancy means a lot. First, the baby in the womb is now a fully formed little person with certain skills and reactions. Second, it is time to go on maternity leave. Third, childbirth is approaching.

What is your baby like now? During an ultrasound, you can see not only the baby’s facial features but also how they breathe, how they are preparing to perform their first independent movements and breathing outside the womb.

30 weeks — fetal development

The “mature” stage of pregnancy has begun. The baby can clench fists during sleep, shrug shoulders, frown, and stretch. The baby understands you and reacts to things they like or dislike. For example, the baby may respond positively when you stroke your belly and negatively when you sit in an uncomfortable position or are in a smoky room.

If development is normal, the baby’s eyes are wide open and able to move within the eye sockets. The baby reacts to light passing through the skin and abdominal muscles — the stronger the light, the stronger the kicks. The baby’s hair continues to grow, sleep and wake cycles are established, and the lungs are preparing for independent function. At the 30th week, the baby’s brain mass increases, and the number and depth of folds increase. The cerebral cortex will fully develop after birth.

Baby’s weight at 30 weeks

At this stage, the baby weighs approximately 1.4–1.5 kg and measures about 37–38 cm in length. The baby has grown large, yet still changes position inside the womb. There are about two more weeks during which the baby can move freely. After that, the baby will assume a stable position — either head down or breech.

30th week — movements

At 30–31 weeks, it is important to pay close attention to sensations, movements, pulling feelings, and kicks. To assess the baby’s activity and ensure proper development, you should monitor the time intervals between movements and perform movement counts: at least 6 movements during active periods

Six-hour count: at least 10 movements

Twelve-hour count: at least 24 movements

“A very hairy baby”

At the 30th week, the baby begins to lose the fine body hair. Sometimes part of it remains, and the baby may be born with noticeable hair. This is completely normal — some babies are born with hair, others without.

How the mother feels

Because the baby has grown significantly, many women experience discomfort at the 30th week. Internal organs are compressed, movements become slower, posture changes, and walking may resemble a waddling gait.

Despite changes in balance, it is important to maintain good posture. Metabolism is so active that you may feel overheated even in cool weather, and sweating increases.

In the final trimester, anemia may develop, and long red stretch marks may appear on the abdomen. The uterus rises high — about 7.5–10.2 cm above the navel and 29–30 cm above the pubic symphysis. This position pushes against the diaphragm and heart, causing shortness of breath.

Low amniotic fluid at 30 weeks

At this stage, careful attention to your condition is essential. Submit tests on time, undergo ultrasounds, and follow your obstetrician’s recommendations to prevent potential complications.

Low amniotic fluid may be diagnosed if the amniotic fluid volume drops below 500 ml. This may be caused by absorption or production issues and can indicate maternal health problems. Such a diagnosis is made only after thorough examination, followed by appropriate treatment.

Time for maternity leave

The 30th week marks the official start of maternity leave according to current legislation. This time should be dedicated to rest, sleep, and walking.

Many women tend to overdo things during maternity leave — either trying to complete every unfinished task or sleeping excessively. Remember: rest and inactivity are not the same. Stay moderately active, prepare for childbirth, and remember that maternal fatigue also affects the baby. You both need strength, health, and energy.
