Your baby’s kicks grow stronger

What to expect this week

Your baby's getting stronger by the day. At 29 weeks, they're about the size of a butternut squash, weighing in around 2.6 pounds and measuring roughly 15 inches from head to toe. Their muscles are developing rapidly, and those kicks and punches you're feeling? They're only getting more pronounced.

Their brain is also developing quickly. Billions of neurons are forming connections, and their brain is starting to control body temperature and regulate breathing patterns. While they’re still practicing breathing amniotic fluid, their lungs are preparing for that first breath of air.

You might notice your energy dipping. As your belly grows, your body is working overtime to support your baby’s development. It’s common to feel more fatigued than usual, especially as sleep becomes trickier to navigate.

Braxton Hicks contractions could start. These are practice contractions that prepare your body for labor. They’re usually irregular and painless, but if they become regular or intense, it’s worth checking in with your provider.

Your baby’s senses are sharpening. They can now sense light filtering through your belly and may turn away from bright sources. Their taste buds are also developing, influenced by the foods you eat (hello, mild amniotic fluid flavors!).

Things to be aware of

Swelling is common, but watch for sudden changes. Mild swelling in your feet and ankles is normal due to increased blood volume and pressure on your veins. However, sudden or severe swelling, especially in your hands or face, could signal preeclampsia and should be mentioned to your provider.

Heartburn might ramp up. As your uterus grows, it pushes against your stomach, causing acid reflux. Eating smaller meals, avoiding spicy foods, and propping yourself up with pillows can help.

Pelvic pressure is increasing. Your baby’s position and growing weight can cause a feeling of heaviness or pressure in your pelvis. While this is normal, sharp or persistent pain should be discussed with your provider.

Shortness of breath can happen too. As your uterus expands, it presses against your diaphragm, making it harder to take deep breaths. Taking it slow and practicing good posture can help ease this.

What might happen

Your third-trimester checkups are on the horizon. Many providers start scheduling appointments every two weeks around now. These visits often include checking your blood pressure, measuring your belly, and listening to your baby’s heartbeat.

You might have the Group B Strep test soon. Around weeks 35–37, your provider will likely test for Group B Strep bacteria, which can affect your baby during delivery. If positive, antibiotics during labor can help protect your baby.

It’s a good time to start thinking about your birth plan. Whether you’re aiming for a natural birth, planning an epidural, or considering other options, jotting down your preferences can help guide conversations with your provider.

Your baby’s movements will become more predictable. As they grow, their patterns of activity, like kicking after meals or during quieter times, might become more noticeable. Tracking these can reassure you (and entertain you!).

If you’re planning to return to work, start thinking about childcare options. Many parents find that researching and securing childcare early helps ease the transition postpartum.
