Introducing LEARN Intensives, a new live virtual event series from ZERO TO THREE. Inspired by the innovation and thought leadership of the LEARN Conference, these interactive deep-dive sessions bring timely topics, emerging research, and leading experts directly to you. 

Infant learning is shaped by the environments we create. This session explores how thoughtfully designed infant rooms can support autonomy, movement, and discovery. Participants will examine how restrictive equipment can limit development and consider alternatives that promote active exploration. Through examples and guided reflection, participants will learn how to design “tiny destinations” that offer meaningful visual, sensory, and physical experiences tailored to each child’s developmental level. Emphasis will be placed on creating flexible environments that evolve as infants grow and develop.

Presenters:

• Rebecca Berlin, PhD, President, Gryphon House 
• Sandra Duncan, EdD, Author and Consultant 

When a young child’s behavior raises concern, how do we know whether it is a passing phase or a sign of something deeper? In Does Time Heal All, the authors challenge the belief that troubling early behaviors will simply resolve with time and instead argue for early identification and treatment when true psychological distress is present, especially while the brain is most adaptable. Through rich case studies and clinical insights, the book explores the complex interplay of genetic, biological, psychological, and cultural factors that shape development, offering a nuanced look at the fine line between intense but typical behavior and symptoms that require therapeutic intervention.
