In this insightful discussion, Professor Jagoda Cieszyńska Rożek explores the critical factors influencing early childhood brain development in the modern world. The central theme revolves around how contemporary lifestyle choices—such as early screen exposure, highly processed diets, and sedentary habits—are reshaping and often hindering children’s neurological, cognitive, and social growth. The conversation highlights the urgent need for early intervention and a return to foundational, relational interactions to foster healthy intellectual development.

The Harmful Effects of Early Screen Time

A major finding presented is that introducing smartphones and tablets to children under three years old is deeply detrimental. Rather than offering educational value, screens disrupt the formation of neural connections. Screen time drastically reduces eye movement compared to real-world observation, impairing the frontal lobe, which regulates personality and rule adaptation. Furthermore, infants cannot recognize 3D objects on a 2D screen, and relying on devices prevents the crucial development of the amygdala, which relies on human facial interactions to learn social cues and emotional regulation.

Movement, Diet, and Speech Acquisition

The podcast debunks the common myth that boys naturally develop speech later than girls, emphasizing that any delay in speech limits a child’s cognitive start in life. The development of speech is intimately tied to physical movement; as children crawl and walk, they orient themselves to spatial sounds and build the motor plans required for articulation. Additionally, the modern trend of feeding children soft, blended foods prevents the development of the jaw muscles needed for proper articulation. Introducing hard foods early, like bread crusts, is vital for speech clarity and gut health, which is directly linked to brain function.

Early Intervention and Bilingualism

Professor Cieszyńska Rożek strongly advises against the “wait-and-see” approach for developmental delays or genetic conditions like Down Syndrome and Autism. Early, targeted stimulation before the age of one can effectively rewire the brain and set a child on a healthy developmental path. Regarding language, true bilingualism is highly beneficial for brain development, provided it follows the “one parent, one language” rule. However, introducing a foreign language in preschool before a child has mastered their native tongue can cause severe learning and emotional difficulties, particularly for children with existing speech delays or a high risk of dyslexia.

Rethinking Education and Parenting

The educational system relies heavily on outdated, stress-inducing metrics like grades and forced competition, which often lead to anxiety and depression in young students. Instead, children require intrinsic motivation based on curiosity and play. Ultimately, healthy development is rooted in strong parental relationships. Parents are encouraged to model positive behaviors—such as putting away their phones and reading physical books—and to engage their children in everyday household chores, which build responsibility and adaptive skills essential for future success.

Mentoring question

How can you adjust your daily routines to provide more meaningful, screen-free interactions that support a child’s natural cognitive and emotional development?
