Adolescent mothers (AMs) often experience limited academic and financial attainment and higher rates of mental health disorders, which may affect their relationships with their children. Although children of AMs are at higher risk for developmental delays, there is no clear evidence of the relationships between mother characteristics and child outcomes. This descriptive study explored AMs' and their children's sociodemographic characteristics and language skills, home literacy environment, and the quality of mother-child interactions. Eight AM-child dyads were recruited from local school districts. Data were collected through questionnaires, standardized measures of language, and mother-child interactions. Most AMs demonstrated below-average language skills and most children had language scores that fell within the average range. AMs demonstrated strong affectionate behaviors, and emerging responsive, encouraging, and teaching behaviors when interacting with their children. This study provides unique data on AMs' language characteristics that have not been clearly published in the literature.
