Autism Spectrum Disorder (ASD) can be diagnosed as early as age 2. The earlier a child receives intervention, the better the long-term outcomes. For parents and caregivers, recognizing the red flags for autism in a 2-year-old is key to seeking early help and support.

Red Flags for Autism in a 2-Year-Old:

Delayed Speech or Lack of Speech: A 2-year-old with autism may have limited or no verbal communication, or might not be using simple words like “mama” or “dada.”
Limited Social Interaction: Avoidance of eye contact, lack of response to their name, or a lack of interest in playing with others or engaging in joint attention (e.g., pointing at objects).
Repetitive Behaviors: Engaging in repetitive motions, such as hand-flapping, rocking, or lining up objects.
Sensory Sensitivities: Overreacting to sounds, textures, or lights, or displaying an unusually high tolerance for pain.
Difficulty with Transitions: Struggling to cope with changes in routine or environment, often resulting in tantrums or distress.
