This project will test the feasibility and acceptability of a novel approach to language intervention based on Milieu Teaching (Milieu Teaching-AV) that encourages looking to audiovisual speech cues for infants with autistic older siblings (Sibs-autism), who are highly likely be diagnosed with autism or developmental language disorder (DLD). The main question\[s\] it aims to answer are:
1. Can caregivers be trained in Milieu Teaching-AV, such that they are using the trained strategies in play with their infant children?
2. Do caregivers find these procedures to be acceptable and feasible to use in their everyday life.
