Early Autism Sign Checker – Free Development Observation Guide for Parents (0–24 Months)

If you have noticed something different about your baby’s development and found yourself searching at midnight — you are not overreacting. You are paying attention. Our free Early Autism Sign Checker is not a diagnostic test. It is a personalized development observation guide that helps you understand what you are seeing, put it in context, and know exactly what to do next — whether that is practicing a few simple games at home this week or calling your pediatrician tomorrow morning.

The tool uses age-adaptive questions based on CDC and AAP developmental milestones for babies 1 to 24 months old. You tell us your baby’s age, describe what is worrying you in your own words, answer a short set of observable behavior questions and select any relevant context — premature birth, hearing concerns, bilingual home, or family history. The result gives you a plain-language summary of what your observations suggest, a list of things that can look similar to autism signs such as hearing differences or bilingual language delay, home activities to try this week, and a copy-paste script to use at your next pediatric visit.

According to the Centers for Disease Control and Prevention, early signs of autism can appear before 18 months and early intervention significantly improves outcomes. The American Academy of Pediatrics recommends autism-specific screening at 18 and 24 months — and sooner if a parent or clinician has concerns. You do not need to wait for a scheduled appointment to raise a concern, and in most US states you can contact Early Intervention directly without a diagnosis.
