This study follows a Vygotskian approach to investigate the influence and relatedness of several scaffolding behaviors for mother-infant dyads of both typically developing infants and infants with disabilities and how early intervention may influence the dyads through the home visiting process. For this primarily low-income sample, maternal participation during play did not enhance the infants\u27 play. The relation of infant level of play with maternal education, income, and the maternal involvement variables of level of play and use of scaffolding varied with the disability status of the infant. Home visitor support of mother-infant interaction did not appear to influence maternal involvement during play, except that mothers of infants with disabilities whose home visitors spent more time with just the infant played at a higher level
