Research shows early intervention is highly effective for young autistic children. A study published in *Pediatrics* found the Early Start Denver Model, which combines ABA methods with relationship-based approaches, significantly improves outcomes. The National Clearinghouse on Autism Evidence and Practice identifies 28 evidence-based practices, including behavioral and developmental interventions like DIR/Floortime. Early intervention (at least 2 years before school) can lead to major skill gains—some children even integrate successfully into mainstream education.

The key is starting early with structured, evidence-based support tailored to the child's needs.
