With schools shut by the global pandemic, a mother – whose unconventional take on parenting sees her children shun exams, pick their bedtimes and decide what to eat – is providing free "emergency kits" for home education to moms and dads across the world.

A champion of "unschooling" – where children learn only what they want to – Dayna Martin, 46, of Miami, Florida, never punishes her offspring, Devin, 20, Tiffany, 18, Ivy, 15 and Orion, 12, and lets them schedule their own days and make their own decisions.
