How Your Child's Environment Shapes their Behavior, Focus and Learning

Have you ever walked into a room and immediately felt tense, scattered, or like you just wanted to leave? Now imagine your child feeling that way at school — or in their own bedroom — every single day. In this episode of The Education Breakdown, host Sarah Keiger sits down with Kirsten Horton, child development and learning environment specialist and founder of Joyful Learning Environments. With nearly two decades in early childhood education, Kirsten is one of the most knowledgeable voices out there on a topic most parents and educators have never thought about: how the physical environment around children directly shapes their behavior, emotional regulation, focus, and academic performance. Whether you're a classroom teacher, a homeschooling parent, or someone who just wants their home to work better for their kids, this episode is packed with research-backed, budget-friendly strategies you can implement today.
