Great question! Research shows that more therapy time can lead to better outcomes for young autistic kids, especially when started early. A study found that toddlers receiving 20 hours per week of early intervention (plus 5 hours of parent-led therapy) showed significant improvements compared to community-based programs (Autism Speaks). Early ABA therapy, typically between 18 months to age 5, takes advantage of the brain's high neuroplasticity during this critical window (Apex ABA). However, quality and consistency matter just as much as quantity—targeted, evidence-based approaches like ESDM or ABA tend to yield the best results.
