Children learn at an early age, mostly through educational and peer interactions, what it means to be a boy and what it means to be a girl, and are quick to demonstrate that they understand these roles. This notion of "doing" gender involves differentiating between boys and girls from the day they are born and perpetuating the discourses of gender difference. The idea of dualism of the genders are misconstrued by dominant ideology and feeds into social norms of masculinity. Children learn and show development of gender identity as an ongoing process, based on social situations. Gendered toys can play a large role in demonstrating the preferred actions and behaviour of young boys in early childhood. The male role is also reinforced by observing older boys and reactions of authority figures, including parents. The promotion of idealized masculine roles emphasizing toughness, dominance, self-reliance, and the restriction of emotion can begin as early as infancy. Such norms are transmitted by parents, other male relatives, and members of the community. Media representations of masculinity on websites such as YouTube often promote similar stereotypical gender roles.
