The study aims to use a special video camera to check if 9-month-old babies might have autism spectrum disorder (ASD) or other developmental delays. This camera tracks how babies look at social scenes, like other kids playing. Parents are asked to join the study during their baby's regular pediatric visit. If they join, babies will have an eye-tracking session while parents complete health forms. If any signs of delay are found, children may have a detailed check-up with experts between 18-26 months old. Even if no signs are found, some children might be invited for an assessment. Parents will receive feedback about their child's development.

• Study involves regular check-ups and filling out forms until the child is 24 months old.
• Children must be 8-10 months old, generally healthy, and parents must give consent.
• About 10% of children without delay signs will still be assessed.
