As a new mom, you are curious about everything related to your child’s development. One of the questions you may be asking is when your baby’s nervous system is fully developed. This is a crucial question because your baby’s nervous system controls everything from breathing, digestion, and movement to emotions, thoughts, and behaviors. In this article, we will explore when a baby’s nervous system is fully developed and what you can do to support its development.

What Is the Nervous System?

The nervous system is a complex network of nerves and cells that transmit signals between different parts of the body. It has two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS).
The CNS consists of the brain and spinal cord, while the PNS includes all the nerves that extend from the brain and spinal cord to the rest of the body. The PNS is further divided into the somatic nervous system and the autonomic nervous system. The somatic nervous system controls voluntary movements, while the autonomic nervous system controls involuntary functions such as breathing, heart rate, and digestion.
When Does the Nervous System Develop?
The nervous system begins to develop very early in pregnancy. In fact, the neural tube, which eventually becomes the brain and spinal cord, forms just three weeks after conception. By the end of the first trimester, the basic structures of the brain and spinal cord are in place.
However, the nervous system continues to develop throughout pregnancy and even after birth. The brain undergoes rapid growth during the third trimester and continues to develop in the first few years of life. By the age of three, the brain has reached about 80% of its adult size.
When Is the Nervous System Fully Developed?
The nervous system is not fully developed at birth. In fact, it continues to develop throughout childhood and adolescence. However, there are certain milestones that indicate when key aspects of the nervous system have reached maturity.
The myelin sheath, which is a protective coating around nerve fibers that helps to improve nerve conduction, continues to develop until about age 25. This is why some aspects of brain function, such as decision-making and impulse control, may not fully mature until early adulthood.
In terms of the autonomic nervous system, the sympathetic and parasympathetic branches are both active at birth. However, they may not be fully coordinated until about six months of age. This coordination is important for regulating heart rate, breathing, and digestion.
What Can You Do to Support Your Baby’s Nervous System Development?
As a parent, you play a crucial role in supporting your baby’s nervous system development. Here are some things you can do:
- Provide a safe and nurturing environment
- Offer plenty of love and affection
- Encourage physical activity and play
- Provide a healthy and balanced diet
- Read and talk to your baby to encourage language development
- Limit exposure to electronic screens
- Get regular checkups with your pediatrician
