Your baby or toddler's brain is not a muscle, however...
It consists of neurons and glial cells, rather than muscle fibers. Although it isn't a muscle, it functions similarly by requiring exercise, as it can develop and adapt (neuroplasticity) through effort and stimulation.
That is why it is important to start stimulating your baby's visual and auditory senses as early as possible.
Your baby's brain grows exponentially when they learn their ABCs, math, vocabulary, and encyclopedic knowledge.
Early learning experts recommend parents start teaching their kids before enrolling in kindergarten in order to build their learning foundation.
Let's look into the timeline of brain development in your young child's mind. The foundation of your child's learning capability starts the moment your child is born.
Your baby or toddler's brain development timeline:
Your baby brain development timeline starts from birth. Here is the timeline from 0 to 5 years old:
Birth: The brain is about 25% of its adult size.
Age 1: The brain doubles in size.
Age 3: 80% of the brain's structure takes shape, and it has up to twice as many synapses as an adult brain.
Age 5: The brain is approximately 90% developed, marking a crucial period for foundational cognitive, social, and emotional skills.
The Analogy: The phrase "the brain is a muscle" is a metaphor for neuroplasticity—the ability of the brain to form new neural connections, similar to how muscles get stronger with exercise.
Use it or Lose it: Like muscles, brain function can decline if it is not regularly challenged and used.
Beginning your child's educational journey at an early age is crucial. If you haven't begun yet, its not too late. Simply start now and, most importantly, choose the appropriate teaching method.
Your child can learn math, reading, and develop their encyclopedic knowledge easily. Discover how you can start your baby or toddler's early learning at home.
