Introduction
As a new parent, you must be curious about your baby’s brain development. You want to know when your little one’s brain will be fully developed. After all, the brain is the most vital organ that drives all the functions of the body. In this article, we will answer the frequently asked question, “What week is baby’s brain fully developed?”.
Week by Week Developments
The brain of a baby starts developing as early as three weeks into pregnancy. However, the development process is a complicated one and takes place in different stages. Here is a breakdown of the week-by-week developments of the baby’s brain:
Week 3 to 4
At this stage, the neural tube, which will eventually form the brain and spinal cord, starts forming. The neural tube develops into three primary parts: the forebrain, midbrain, and hindbrain.
Week 5 to 6
The brain starts to develop specific regions, such as the cerebral cortex, brainstem, and cerebellum. These regions will control various body functions such as balance, movement, and coordination.
Week 7 to 8
The baby’s brain is developing rapidly, and the cerebral cortex, the part of the brain responsible for thinking, memory, and consciousness, begins to form.
Week 9 to 12
The brain grows rapidly, and the cerebral cortex starts to take shape. The baby’s brain also starts to produce brain cells at a faster rate.
Week 13 to 16
The baby’s brain continues to develop, and their movement becomes more coordinated due to the development of the cerebellum.
Week 17 to 20
At this stage, the baby’s brain is developing at a rapid pace, and their senses start to develop. The baby can now hear, see, smell, taste, and touch.
Week 21 to 24
The baby’s brain is structurally complete, and their brain cells are starting to communicate with each other.
Week 25 to 28
The baby’s brain is now capable of controlling their body temperature, and their sense of touch is highly developed.
Week 29 to 32
The baby’s brain continues to develop, and they start to learn and remember. Their brain also starts to regulate their breathing and sleeping patterns.
Week 33 to 36
The baby’s brain is almost fully developed, and they are now preparing for life outside the womb.
When Is Baby’s Brain Fully Developed?
It’s hard to pinpoint the exact week when a baby’s brain is fully developed. However, it’s safe to say that it happens during the third trimester of pregnancy. By the time a baby is born, their brain is about 25% of its adult weight. The rest of the development happens after birth.
The Importance of Early Brain Development
Early brain development is crucial for a child’s future. The first three years of life are the most critical for brain development. During this time, a child’s brain is developing rapidly, and the experiences they have can impact their cognitive, social, and emotional development. Providing a stimulating environment and engaging with your child can help promote healthy brain development.
Conclusion
The brain is a critical organ that drives the body’s functions. Baby’s brain development is a complicated process that happens in different stages. It starts as early as three weeks into pregnancy and continues after birth. It’s hard to pinpoint the exact week when a baby’s brain is fully developed, but it happens during the third trimester of pregnancy. Early brain development is crucial for a child’s future, and providing a stimulating environment can promote healthy brain development.
