This article explores Ibn Sina’s (Avicenna’s) philosophical and medical perspectives on the upbringing and mental development of children. Drawing upon his seminal works such as “Kitab al-Qanun fi al-Tibb” (The Canon of Medicine) and “Kitab al-Nafs” (Book of the Soul), the study analyzes how Avicenna integrated psychological, pedagogical, and ethical principles into child development. The research highlights Ibn Sina’s understanding of the interrelation between physical health, moral education, and mental maturity, emphasizing his recommendations on proper nutrition, environmental influence, and emotional balance during early childhood. Through comparative analysis with modern developmental psychology, the study shows that Ibn Sina’s insights anticipated many contemporary theories of child growth, learning, and emotional regulation. The findings confirm that his multidimensional approach, combining medical and ethical aspects, remains relevant to modern educational and healthcare systems aiming to foster holistic development in children.
