Your baby’s brain development starts in your womb. By the time of birth, their brain can register sounds and they can see around. After birth, their brain keeps developing for many years. The more your baby’s brain is exposed to various stimuli, the more they grow. Communicating with your child positively can help their brain develop better.

Stages of Brain Development

First Trimester

Nerve connections are built in their brain, enabling them to move around in the womb. Their neural tube is formed. Neurons and synapses are developed in the spinal cord.

Second Trimester

Nerve connections develop further. Brain tissue is formed during this period. The topmost layer of the brain comprising of Gyri and sulci are formed. A layer of myelin, which helps the brain to process information faster, is formed.

Third Trimester

The cerebral cortex starts to form at the brain stem. This part of the brain will help your child to learn. The brain is now capable of responding to external stimuli like touch, smell, pain, vision, taste, and sound.

First Year

This is the age of quick development. Motor skills develop and they now have perfect vision. Around three months, your baby will be able to recognize and remember. Your baby will also develop language skills during this year. Babies can learn languages faster than adults.

Second Year

Your baby’s vocabulary will increase this year. Your baby is now capable of performing more complex tasks. They are now aware of complex emotions. At this age, they also become aware of their name and reflection.

Third Year

At this age, the brain develops to create more synapses. The child becomes aware of the present and past. Their memory develops and they also start understanding the impact of cause and effect. The reading and writing skills also start developing at this age.

Healthy brain development is stimulated by healthy surroundings, good nutrition, and loving encouragement. Singing, playing peek-a-boo, reading and talking to them will boost their brain development.
