This website describes the program of research that the Language Intervention team at the Juniper Gardens Children’s Project has conducted across a series of research projects documenting the use of naturalistic communication interventions by parents and early interventionists to promote the communication of infants and toddlers. Extending upon the early groundbreaking research of Drs. Betty Hart and Todd Risley (1992; 1995), we have collaborated with community partners on projects to increase the language learning opportunities that infants and toddlers have in their home and in child care.
