Home Play-based Intervention for Parents and Infants

The goal of this clinical trial is to learn whether a 12-week home-based intervention (Sociometric Play-based Remediation of Individual Neurodevelopmental Trajectories (SPRINT)) helps support parenting and the development of infants aged 7 - 15 months (at the time they join the study) who were born preterm and/or have a higher family risk of developmental conditions, such as autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), and/or global developmental delay (GDD). The main questions it aims to answer are: * Does taking part in the SPRINT intervention help parents develop parenting skills? * Does taking part in the SPRINT intervention improve infant's thinking skills and/or socio-emotional development? Researchers will compare families who receive the SPRINT intervention with families in a waitlist control group to see whether the intervention leads to greater improvements in parents and their children. Participants will: * Complete questionnaires and in-person assessments, before and after the 12-week period. * Be assigned to either the SPRINT intervention or a waitlist control group and complete the assigned activities for 12 weeks. * Use the SPRINT app, which provides information, guidance and activities for either the SPRINT intervention or waitlist control group.
