It's great you're looking into ABA and ESDM therapies! A recent study looked at how both ABA (Applied Behavior Analysis) and ESDM (Early Start Denver Model) impact children with autism over six months.

The study showed that both therapies led to improvements in core autism symptoms. Specifically, the ESDM group showed greater gains in social reciprocity, while the ABA group excelled in gross motor skills. Both groups improved across language, social interaction, and motor skills.

For broad gains in social skills and language, consider ESDM, especially since it's effective even at lower doses. If you're targeting motor or behavioral skills, ABA might be a good fit, but it often requires a higher intensity. Starting early, especially before 30 months, can lead to lasting benefits!
