Autism Spectrum Disorder (ASD) is typically diagnosed between 18 months and 3 years of age, although signs may appear earlier. Some children show noticeable differences in communication, social interaction, or behavior by their first birthday. Others may develop typically and then begin to regress in skills around age 2.
Early signs of autism can include:
-
Limited eye contact
-
Delayed speech or language
-
Repetitive behaviors (like hand flapping)
-
Lack of interest in playing with others
-
Not responding to their name
The earlier autism is identified, the sooner a child can begin intervention services like ABA therapy, which greatly improves long-term outcomes. Pediatricians typically screen for autism at regular checkups around 18 and 24 months, but parents who notice delays or behavioral differences should speak up sooner.
At Little Champs ABA, we help families recognize early signs and connect with diagnostic resources. Our personalized therapy programs support development in communication, social skills, and independence from an early age.
