Pregnancy Week 25
Your baby is growing quickly this week. The brain and nervous system continue to mature, the lungs are developing further, and your baby’s movements are becoming stronger and more coordinated. Your baby is also beginning to gain more body fat.
Your Baby This Week
Brain & Nervous System Development
At week 25, your baby’s brain continues developing rapidly. Different areas of the brain are becoming more specialized, while the nervous system continues improving communication between the brain, spinal cord, and body.
These changes help your baby’s movements become increasingly coordinated.
Lung Development
Your baby’s lungs continue developing and preparing for breathing after birth. The airways are becoming more developed, while the lungs continue producing surfactant.
The lungs are still immature and require additional development during the remaining weeks of pregnancy.
More Body Fat
Your baby continues accumulating fat beneath the skin. This gradually gives the body a fuller appearance and will become increasingly important for maintaining body temperature after birth.
Stronger Movements
Your baby is becoming increasingly active. Kicks, stretches, rolls, and other movements may be easier for you to notice.
Brain, Lungs & Movement
Your baby is about the size of a rutabaga. The brain and nervous system continue developing while the lungs mature and the body gains more fat.
Your Body This Week
Your body continues adapting as your pregnancy progresses toward the third trimester.
Stronger Baby Movements
You may notice more pronounced kicks and movements as your baby grows. Your baby's activity can vary throughout the day.
Growing Belly
Your uterus continues expanding, which may affect your posture, balance, and comfort when sitting or sleeping.
Heartburn & Indigestion
Heartburn and indigestion can become more noticeable as the growing uterus places increasing pressure on the digestive system.
Sleep Changes
Finding a comfortable sleeping position may become more challenging. Supporting your abdomen and legs with pillows may help.
