What a valuable question to ask!
One of the most effective starting points is to approach families with respect, humility, and genuine curiosity rather than judgment. That does not mean compromising on children’s safety, education, or wellbeing. It means building enough trust for real conversation.
It often helps to work through trusted local voices such as teachers, health workers, women leaders, elders, or faith leaders who understand the community and can help frame education and child wellbeing in ways families can hear. It is also useful to focus on shared goals like safety, stability, health, and a better future for children.
At the same time, families often need support, not just advice. If early marriage is tied to poverty, insecurity, or lack of school access, then practical help like transportation, school support, mentoring, or community-based alternatives may matter as much as the conversation itself.
I also think it is important to create safe space for girls and young people to be heard directly. And while cultural sensitivity matters, it should never mean avoiding clear advocacy for a child’s rights and protection.
