Pregnancy Week 30
Your baby is growing quickly as the third trimester continues. The brain is developing rapidly, the lungs continue to mature, and your baby is gaining more body fat and strength. Movements may feel stronger as your baby grows.
Your Baby This Week
Rapid Growth
At week 30, your baby continues gaining weight and growing longer. More fat is developing beneath the skin, giving your baby a fuller appearance.
This growth will continue throughout the final weeks of pregnancy as your baby prepares for birth.
Brain Development
Your baby’s brain continues developing rapidly. The surface of the brain is becoming more folded, creating additional areas for continued development.
The nervous system is also becoming increasingly mature and helps your baby coordinate movements and respond to different sensations.
Developing Lungs
Your baby’s lungs continue maturing. The airways and tiny structures needed for breathing continue developing, while surfactant production increases.
The lungs still need additional time to mature before birth.
More Body Fat
Your baby continues storing more fat beneath the skin. This fat will provide energy and help regulate body temperature after birth.
Rapid Growth
Your baby is about the size of a cabbage. The brain continues developing rapidly while your baby gains more fat, strength, and weight.
Your Body This Week
Your body continues adapting to the increasing demands of the third trimester.
Growing Belly
Your uterus continues expanding as your baby grows. You may find that bending, walking, or changing positions takes more effort than before.
Stronger Movements
Your baby's movements may become more noticeable and predictable. You may begin recognizing your baby's periods of activity and rest.
Heartburn & Indigestion
Heartburn and indigestion can become more frequent as the growing uterus places pressure on the stomach.
Fatigue
The physical demands of pregnancy, changes in sleep, and your growing baby may leave you feeling more tired.

Frequently Asked Questions
How big is my baby at Week 30?
Your baby is approximately the size of a cabbage. Exact measurements vary depending on the timing of development.
What is developing during Week 30?
Your baby’s brain continues developing rapidly, while the lungs, nervous system, muscles, and bones continue maturing. Your baby is also gaining more body fat and weight.
Is my baby gaining weight quickly now?
Yes. Weight gain becomes increasingly important during the third trimester as your baby stores more fat and prepares for life outside the womb.
Why do my baby's movements feel different?
As your baby grows and the available space becomes more limited, movements may feel different. You may notice stronger kicks, rolls, stretches, or pressure rather than large changes in position.

Your baby may be head-down at Week 30, but there is still time for the position to change. Many babies settle into their final position later in pregnancy.

If fatigue is severe or accompanied by other concerning symptoms, discuss it with your healthcare professional.
