What Are the Signs of Autism in a 4-Year-Old?

Autism Spectrum Disorder (ASD) affects each child differently, but by age 4, certain developmental and behavioral signs may start to stand out. Common indicators include delayed speech or limited communication, such as not forming sentences or repeating the same words. A 4-year-old with autism may also avoid eye contact, prefer playing alone, or show strong interests in specific toys or routines.

Other signs include difficulty understanding emotions, sensory sensitivities (like being upset by loud noises or certain textures), and repetitive behaviors such as hand flapping, rocking, or lining up toys. Some children may also struggle with transitions or changes in routine.


Early identification is key, starting ABA therapy can help children build communication, social, and daily living skills that set them up for long-term success.


At Connect n Care ABA, we provide personalized, in-home ABA therapy in North Carolina, focusing on each child’s strengths and supporting their unique growth at every step.
