During the third trimester, your baby’s brain is growing at a rapid pace. The cerebral cortex, which is responsible for processing information from the senses, is developing rapidly. This means that your baby will be able to hear and respond to sounds outside the womb, and may even recognize your voice. They will also be able to see light filtering through your belly, although their vision will still be very limited.
Respiratory System
Your baby’s lungs will continue to develop during the third trimester, which is important for their ability to breathe on their own after birth. At around 32 weeks, they will begin to produce a substance called surfactant, which helps to keep the air sacs in the lungs from collapsing. This is a critical step in their respiratory development, and without surfactant, they would not be able to breathe properly.
Muscle and Bone Development
As your baby grows and prepares for birth, their muscles and bones will continue to develop. By the third trimester, their bones will be fully formed but will still be soft and pliable, which will make it easier for them to pass through the birth canal. Additionally, their muscles will become stronger, which will help them to move and prepare for life outside the womb.
Sleep-Wake Cycles
During the third trimester, your baby will begin to develop regular sleep-wake cycles. You may notice that they are more active at certain times of day, and sleepier at others. This is a sign that their brain is developing the ability to distinguish between night and day, which will be important for their sleep patterns after birth.
