Chapter 4 presents intersectionality theory to explain the cumulative and interactive gender-based and child-based discrimination encountered by the girl child. It explores interactive intersectional discrimination, whereby each infringement on the rights of the girl child leads to a series of violations that occur throughout her childhood. Chapter 4 conducts a case study of the practice of son preference and daughter devaluation in the private sphere leading to girl child neglect, which in turn weakens her access to education and economic empowerment. It also discusses the negative impact of sexualized social and dress codes, notably the over-sexualization of girls in mainstream and social media, including Instagram and TikTok, leading to digitized dysmorphia, eating disorders, violence against girl children, sex trafficking and child pornography. The chapter concludes that the international legal framework cannot protect the girl child unless the interactive intersectional discrimination she experiences is acknowledged.
