It's great you're looking into ABA and ESDM therapies! Recent studies show both can lead to significant improvements for children with autism, especially in cognition, language, social skills, and adaptive behaviors.

One study (PMCID12116431) found that ESDM showed greater gains in social-receptive skills, while ABA excelled in gross motor skills. So, the best choice might depend on your child's specific needs. For example, if your child needs help with social skills, ESDM might be a good fit. If adaptive skills are a focus, ABA could be beneficial.

Also, parent involvement and consistent hours (aim for 15-25 hours/week) can really boost the effectiveness of either therapy. I hope this helps!
