Families are one of the fastest-growing groups affected by homelessness in the U.S. Very young children are profoundly affected by the loss of a consistent living situation, most especially in the first 3 years when routine and familiarity confer a sense of safety and security. The stress of homelessness--and the multiple traumas that frequently accompany the search for housing--can also have serious and detrimental impacts on the parent-child relationship. Infant-toddler programs can mitigate these effects through thoughtful, individualized programming that reflects the needs of families experiencing homelessness while keeping a young child's healthy development at the center of its focus.
