Signs of Autism

Autism looks different for every person. Some individuals may show clear signs early in life, while others may not be identified until later childhood, adolescence, or even adulthood. Autism is a spectrum, and signs can vary widely in type and intensity.

Early Signs

A baby or young child with autism may:

  • Not respond to their name by 12 months of age.
  • Not point at objects (example: a plane flying overhead) to express interest.
  • Not play “pretend” games (example: “feeding” a doll) by 18 months.
  • Experience distress from certain textures or sensory overload of bright, flashing, or noisy toys.
  • Limit eye contact.
  • Have delayed speech or language skills.
  • Not smile back at or wave to others by 12 months of age.
  • Experience physical delays such as not holding or grasping objects and delayed crawling.

Remember, developmental milestones vary from child to child, and these signs alone do not confirm a diagnosis.

Other Signs

Communication & Social Interaction

Some individuals may:

  • Communicate verbally, minimally, only non-verbally, or not at all.
  • Have difficulty starting or maintaining conversations.
  • Use language in unique ways (such as repeating words or phrases).
  • Prefer limited eye contact or use alternative ways to engage.
  • Find social rules or unspoken expectations confusing.

Social Connection & Play

Some individuals may:

  • Prefer to play or spend time alone.
  • Interact differently with peers or adults.
  • Show strong interest in specific topics or activities.
  • Engage in imaginative play in unique or repetitive ways.

Sensory Processing

Many people with autism experience sensory input differently than people who do not have autism. This may include:

  • Sensitivity to sounds, lights, textures, smells, or tastes.
  • Seeking out certain sensory experiences (movement, pressure, sounds).
  • Becoming overwhelmed in busy or noisy environments.

Repetitive Behaviors & Routines

Some individuals may:

  • Repeat movements, sounds, or phrases.
  • Strongly prefer routines or predictability.
  • Experience distress when routines change.
  • Focus intensely on specific interests.

Emotional Regulation & Daily Living

Some individuals may:

  • Experience intense emotions or difficulty regulating them.
  • Have challenges with transitions or unexpected changes.
  • Need support with organization, planning, or daily tasks.

A Note on Strengths

Autism can also come with many strengths! Many individuals with autism demonstrate creativity, deep focus, honesty, strong memory, unique problem-solving skills, and a powerful sense of justice. These traits (and others) are just as important as any challenges.

Seeing Signs?

If you notice some of these signs in yourself or someone you care about, it doesn’t automatically mean autism. However, it may be helpful to explore further. Thinking about a diagnosis? Check out our resources on diagnosing autism.
