29 Weeks Pregnant: Growth and Strength Continue

At 29 weeks pregnant, your baby is about the size of a butternut squash and continuing steady growth in the third trimester. If you are searching for 29 weeks pregnant baby size, symptoms, or development, this week brings continued brain growth, strengthening muscles, and increasing movement.

Your baby is becoming more active and responsive as the nervous system continues maturing.

At a Glance:
29 Weeks Pregnant
  • Baby size: About the size of a butternut squash
  • Trimester: Third trimester
  • Key hormonal shift: Progesterone remains elevated, supporting pregnancy but sometimes contributing to fatigue and digestive changes.
  • Common symptoms: Stronger kicks, back discomfort, swelling, heartburn, leg cramps, sleep challenges
  • Doctor visit: Many providers continue biweekly prenatal visits during this stage
  • Emotional theme: A growing awareness that the final months of pregnancy are approaching.

At 29 weeks pregnant, your baby measures about 38 to 39 cm from head to heel and weighs around 1.15 kilograms (about 2.5 pounds).

Here is what is happening:

  • The brain continues developing rapidly with increasing neural connections.
  • The lungs continue maturing and producing surfactant.
  • Muscles and bones continue strengthening.
  • Movements become stronger and more coordinated.
  • The baby can respond to sounds and voices from outside the womb.
  • Sleep and wake cycles are becoming more established.
  • Body fat continues accumulating, helping prepare the baby for life outside the womb.

Your baby is continuing to gain strength and coordination with each passing week.

What Is Happening in Your Body at 29 Weeks Pregnant

As the uterus expands, your body continues adjusting to support your baby’s growth.

You may notice:

  • Stronger kicks and rolling movements
  • Back pain or pelvic pressure
  • Swelling in the feet or ankles
  • Heartburn or indigestion
  • Leg cramps
  • Difficulty finding a comfortable sleeping position

Blood volume remains elevated to support the placenta and developing baby.

Emotional and Nervous System Changes

During the third trimester, emotional awareness may shift as the reality of birth approaches.

You may experience:

- Excitement about meeting your baby
- Increased focus on preparing for birth
- Moments of fatigue or emotional fluctuation

Taking moments for calm breathing or rest can help support emotional balance during this stage.

3 Focus Areas This Week

Support circulation
Gentle movement such as walking or stretching can help reduce swelling and support circulation.

Prioritize sleep comfort
Using pillows for side sleeping may help improve comfort and reduce pressure on the back.

Stay hydrated and nourished
Hydration and balanced nutrition remain essential as your baby continues gaining weight.

Weekly Calm Practice

Place one hand on your belly and take a slow inhale through your nose.

As you exhale, allow your shoulders to soften.

Take another steady breath and notice the quiet movement within you.

Silently say to yourself:

“My body is supporting this growing life.”

Stay with this calm moment for a few breaths.
