When toddlers show signs like hyperactivity, tantrums, or language delays, it can be hard to tell if it's ADHD, autism, or both. Dr. Mary Barbera shares how to spot early signs, understand the key differences, and take action before a diagnosis.

Whether your child has ADHD, autism, or early red flags, early support builds language, reduces problem behaviors, and leads to better long-term outcomes.
