Brain research has confirmed what many early care and education professionals have known all along--warm, nurturing relationships among babies, toddlers, and their caregivers support children's development. The nurturing adult-child interaction that supports children's development is called "responsive care". Responsive care is supported by small adult-child ratios and primary care systems. Furthermore, small adult-child ratios support the child observation strategies that are central to responsive care. It is important for caregivers to "intentionally" implement responsive interactions because this type of care has been shown to be particularly important for encouraging babies' social-emotional development. How do early childhood educators provide nurturing care to infants and toddlers that supports their long-term development? This article outlines eight practical strategies, called the Ps of the Responsive Caregiving Process.
