The human brain is arguably the most complex biological system with a highly dynamic lifespan and encompasses continuity and changes at both structural and functional levels. Especially during the childhood, it's crucial to stimulate the growing brain and keep it well-exposed to positive stimuli.

"There is rapid brain growth in the initial two years of life that extends until eight years of age. This is accompanied by a slow rate of functional maturation that extends into early adulthood. The initial years form the basis for future learning, emotional wellbeing and contributes substantially to health and life success. Nurturing and responsive care forms a keystone in supporting and stimulating brain development," Dr Kavita Gohil, Paediatrician, Zen Multispeciality Hospital, Chembur told IANSlife.
