At week 30, your baby is about the size of a large cabbage — roughly 15.7 inches long and nearly 3 pounds. The third trimester is officially underway, and your baby’s brain is growing so fast that it is forming distinct regions for processing sights, sounds, and movement. You may notice your belly looking lopsided at times as your baby shifts position, and those kicks are getting stronger with more defined little fists and elbows. For you, this week often brings a mix of excitement and exhaustion: your body is working hard, and resting when you can is not laziness — it is part of the job. Biweekly prenatal visits are now the norm, keeping a close eye on your blood pressure and your baby’s growth.

👶Baby Development at Week 30

Your baby’s brain is developing rapidly this week, with distinct folds and grooves allowing different regions to specialize. The brain can now regulate body temperature, and the bone marrow has fully taken over production of red blood cells — an important job it will keep for life. Your baby’s eyes are open during waking hours, and the irises can react to light, though true color vision will not develop until after birth.

The lanugo (fine downy hair) that has covered your baby’s body is starting to shed, though some may remain at birth, especially on the shoulders and back. Vernix, the protective white coating, continues to thicken over the skin. Your baby is practicing swallowing and may even get the hiccups regularly — those rhythmic little jumps you feel are completely normal and a sign of a developing diaphragm.

Your baby’s bone marrow, lungs, and digestive system are all maturing, and the lungs are producing more surfactant, the substance that will keep the air sacs from collapsing after birth. Your baby now weighs enough that if born this week, survival rates are very high with specialized neonatal care — though every additional week inside makes a meaningful difference for lung and brain maturity.

Sleep patterns are becoming more organized, with distinct cycles of REM (dreaming) and deep sleep. Your baby’s five senses are all functional now: tasting the flavors of what you eat through the amniotic fluid, hearing your voice and heartbeat, seeing changes in light, feeling touch, and even smelling. Keep talking and singing — your baby already knows your voice.

🩺Your Body: Common Symptoms at Week 30

▸ Returning Fatigue

First-trimester-style tiredness often comes back as your body works overtime and sleep gets harder. Short naps and going to bed earlier can help you recharge.

▸ Mood Swings

Hormones, physical discomfort, and the reality of an approaching birth can make emotions swing wildly. Talking honestly with your partner or a friend often lightens the load.

▸ Braxton Hicks Contractions

These painless, irregular tightenings of the uterus may become more noticeable. They are practice contractions — changing position or drinking water usually makes them stop.

▸ Swollen Feet and Ankles

Your body is retaining extra fluid and your growing uterus slows circulation to your legs. Elevating your feet, avoiding long periods of standing, and staying hydrated can reduce swelling.

▸ Constipation

Slowed digestion and iron supplements can make constipation worse. Fiber-rich foods, plenty of water, and gentle walking keep things moving.

▸ Restless Legs

An irresistible urge to move your legs, often worse at night, affects many pregnant people in the third trimester. Gentle stretching and avoiding caffeine may help.

🏥Medical Tests & Checkups at Week 30

Your prenatal appointments are now every two weeks. Your provider will continue to monitor your blood pressure, test your urine for protein, measure your belly, and check your baby’s heartbeat and position. Fundal height measurements help confirm your baby is growing on track.

If you have risk factors such as high blood pressure, diabetes, or a history of preterm labor, your provider may order a growth ultrasound or begin discussing additional monitoring. Around this time, many providers also start the conversation about your birth preferences in more detail. If you have not yet completed your glucose screening, mention it at this visit — and if you are Rh-negative, confirm your RhoGAM shot was given.

🥗Nutrition & Movement Tips

Add fiber (oats, beans, berries, whole grains) to combat constipation.

Keep drinking 8–10 glasses of water daily to fight swelling and cramps.

Include DHA sources like low-mercury fish twice weekly for brain development.

Eat protein at every meal to support your baby’s rapid tissue growth.

Try prenatal yoga or gentle swimming to ease aches and improve sleep.

Do Kegel exercises daily — strong pelvic floor muscles help during labor.

✅Week 30 Checklist

📌When to Call Your Doctor

Call your provider right away — or head to labor and delivery — if you notice any of these warning signs. It is always better to be checked and reassured than to wait and worry.

Noticeably reduced fetal movement or a change in your baby’s pattern.

Signs of preeclampsia: severe headache, vision spots, sudden swelling.

Regular contractions, pelvic pressure, or fluid leaking before 37 weeks.

Heavy vaginal bleeding or severe, constant abdominal pain.

Fever over 100.4°F (38°C), chills, or burning when you urinate.
