It's great you're looking into ABA and ESDM therapies! Research shows both can be really helpful for kids on the spectrum, especially when started early.

ESDM (Early Start Denver Model) can lead to lasting improvements in language, behavior, and IQ, particularly when delivered intensively to toddlers. It's great for boosting social communication and using play-based methods. ABA (Applied Behavior Analysis) is effective in improving IQ, adaptive behaviors, and language skills, while also reducing challenging behaviors.

Both ABA and ESDM show measurable progress within 6 months of starting! A recent study even suggests that the intensity of therapy (more hours per week) doesn't always equal better results, so it's really about finding the right fit for your child.
