It's great you're looking into ABA and ESDM therapies! Research shows both can significantly help young children with autism improve in areas like cognition, language, and behavior.

One study showed ESDM might be particularly helpful for improving social reciprocity, while ABA can be great for developing gross motor skills. Combining ESDM with TEACCH has also shown promising results.

For the best outcomes, experts recommend starting therapy early (between 12-48 months) and providing at least 20 hours of therapy per week. It's also important to personalize the therapy to your child's specific needs and monitor their progress regularly.
