What’s happening with the baby at 30 weeks pregnant?

Baby's skin

At 30 weeks, your baby’s skin cells are busy producing melanin, the pigment responsible for skin color. While some melanin is present now, most of it develops after birth, and your baby’s permanent skin tone will not be fully established until around 6 months of age. This process is essential for protecting their skin from sunlight and other environmental factors once they’re born.

Baby's hair

The fine hair, or lanugo, that once covered your baby’s body is starting to fall away, leaving smoother skin behind. Meanwhile, the hair on your baby’s head is growing thicker, and you might even be able to guess its color and texture at birth. These changes are preparing your baby for their debut into the world.

Baby's eyes

Your baby can now open their eyes wide and may even respond to bright light by turning their head toward it. Though their vision is still limited, this is an important milestone in their sensory development. By next week, their pupils will begin to expand and contract, letting in more or less light as they adapt to their surroundings.

Respiratory system

Your baby’s lungs continue to mature as they produce surfactant, a substance that keeps their tiny air sacs open and prevents them from collapsing. While their respiratory system is still developing, this preparation will be crucial for breathing air after birth. By the time they reach full term, their lungs will be ready to take their first breath.


How big is your baby at 30 weeks pregnant?

At 30 weeks, your baby is about the size of a large cabbage, measuring approximately 40.5 cm from head to toe and weighing around 1.56 kg. Your baby is growing rapidly, which means they are running out of room in your uterus. You may notice their movements becoming more pronounced but slightly less frequent. Their increasing weight is also adding to the extra pressure you might feel on your back and pelvis.


How is your belly at 30 weeks pregnant?

By 30 weeks, your belly is likely larger and more prominent than ever. As your uterus continues to expand, it pushes against your abdominal wall, causing your belly button to flatten or even pop out. You may also notice stretch marks appearing as your skin stretches to accommodate your growing baby. Your bump might feel tighter, and the skin could become itchy—applying moisturizers can help alleviate some of the discomfort. 


Common symptoms and how to manage them?

1) Fatigue

You may feel more tired than usual as your body works hard to support your growing baby. Try to rest when you can, eat balanced meals, and include light exercise like walking or yoga to boost energy levels. If fatigue feels overwhelming, talk to your healthcare provider to rule out conditions like anemia.

2) Heartburn

The pressure of your growing uterus on your stomach, combined with pregnancy hormones, can cause heartburn. To manage this, eat smaller meals, avoid spicy or fatty foods, and don’t lie down immediately after eating. Drinking water between meals instead of during them can also help. For persistent discomfort, consult your doctor about pregnancy-safe antacids.

3) Swelling

Swelling in your feet, ankles, and sometimes hands is common due to fluid retention and pressure on your veins. Rest with your feet elevated, wear compression socks, and stay hydrated. Avoid standing or sitting for long periods. If swelling is severe or sudden, contact your doctor, as it could indicate a serious condition like preeclampsia.

4) Shortness of breath

As your uterus grows, it puts pressure on your diaphragm, making it harder to breathe deeply. Slow down, take breaks, and avoid activities that overexert you. Sleeping propped up with pillows can also help ease breathing discomfort.

5) Back pain

The extra weight you’re carrying can strain your lower back. To manage back pain, practice good posture, wear supportive shoes, and use a pregnancy pillow for extra support while sleeping. Gentle stretching, prenatal massage, or consulting a physical therapist may also provide relief.

6) Mood swings

Hormonal changes and physical discomfort can lead to mood swings. Practice stress-reducing activities like meditation, prenatal yoga, or journaling. Talk openly with your partner or friends about how you’re feeling, and seek support from a healthcare provider if emotions become overwhelming.

7) Frequent urination

Your baby’s position can put pressure on your bladder, causing you to visit the restroom more often. To manage this, avoid drinking large amounts of fluids before bedtime. However, don’t reduce your overall water intake—hydration remains essential.


Frequently asked questions at 30 weeks pregnant

Can I safely travel during my third trimester?

Traveling at 30 weeks is generally safe if you have a low-risk pregnancy. However, it’s important to consult your doctor before making any plans, especially for air travel. Airlines often have restrictions for pregnant passengers in the later stages of pregnancy. If traveling, keep hydrated, stretch your legs frequently, and carry your prenatal records.

Is it normal to feel less movement from the baby?

It’s common for baby movements to feel different as your baby grows and space becomes tighter in the womb. However, you should still feel regular movement patterns. If you notice a significant decrease in movement, perform a kick count and contact your healthcare provider immediately.

What should I include in my hospital bag?

Now is a great time to start packing essentials like comfortable clothing, toiletries, a nursing bra, baby clothes, diapers, and a phone charger. Don’t forget important documents such as your ID, insurance details, and birth plan if you have one.

How can I prepare for labor and delivery?

Consider taking childbirth classes to understand the stages of labor, pain management techniques, and what to expect during delivery. Now is also a good time to discuss your birth plan with your doctor or midwife. Preparing mentally and physically can help reduce anxiety as the big day approaches.

Is it safe to have sex at 30 weeks pregnant?

For most women with healthy, uncomplicated pregnancies, sex is safe throughout the third trimester. However, you may need to adjust positions for comfort. If you experience bleeding, pain, or other concerns, consult your healthcare provider.

How much weight should I gain by now?

Weight gain varies depending on your pre-pregnancy BMI, but by 30 weeks, most women gain around 8 to 11.5 kilograms. Talk to your doctor about your progress and focus on eating a balanced diet to support your baby’s growth and overall health.

Do I need to worry about preterm labor?

While most pregnancies progress to full term, it’s important to know the signs of preterm labor, such as regular contractions, lower back pain, or fluid leakage. If you suspect preterm labor, contact your healthcare provider immediately.
