Brain development in babies is an incredible natural phenomenon. As primates, our pelvises were larger, and babies were born with bigger brains and more developed cognitive functions. However, as Homo erectus began walking upright, an evolutionary race emerged between the size of women’s pelvises and babies’ brain development. This led to human babies being born underdeveloped, making them among the most helpless species at birth.
In the first three months of life, often referred to as the “fourth trimester,” a baby’s brain will grow by an astonishing 64%. This rapid growth continues, and by age three, 80% of the brain is formed, with the remaining 20% developing over the next two decades.
For new parents, this information may seem overwhelming. Does this mean they must constantly stimulate their babies to ensure optimal development? Fortunately, the process is largely natural. After birth, parents should focus on meeting their baby’s essential needs and their own self-care, trusting that their newborns will learn from the world around them.
Most learning occurs through sensory experiences. Simple daily interactions—light, the aroma of food, a cuddle—already provide an incredible sensory experience for a baby transitioning from the cocoon of the womb. Something as simple as a walk to the park will be a life saver for you and a sensory revelation to your newborn: a dog barking, the smell of the pond, the feeling the fresh air against the baby’s soft skin will all contribute to you newborn brain’s remarkable growth.
As babies get older fostering sensory play is hugely important. Below are some of the key benefits of sensory play and some activity suggestions.
Parents can easily integrate sensory play into daily routines with simple and engaging activities:
Sensory play is more than just fun; it is a fundamental part of childhood development. By stimulating the senses, children gain crucial skills that support their cognitive, motor, and emotional growth. Encouraging a variety of sensory experiences at home and in educational settings helps children develop confidence, resilience, and a deeper understanding of the world around them.
