Identifying autism signs early leads to earlier intervention and better outcomes. While every child develops differently, certain patterns across different ages may indicate the need for evaluation.

Signs in Infancy (0-12 Months)

Limited eye contact during feeding and interaction. Not responding to their name by 9 months. Not babbling by 12 months. Not pointing or waving by 12 months. Limited social smiling. Not following a parent’s gaze to look at objects.

Signs in Toddlers (12-24 Months)

No single words by 16 months. No two-word phrases by 24 months. Limited pretend play. Lining up toys rather than playing with them. Intense reactions to sensory experiences. Loss of previously acquired skills (regression). Limited interest in other children.

Signs in Preschoolers (2-4 Years)

Preference for solitary play. Difficulty with back-and-forth conversation. Echolalia (repeating phrases rather than generating original speech). Intense, narrow interests. Rigid routines with distress over changes. Unusual motor behaviors like toe walking or hand flapping.

Signs in School-Age Children (5+ Years)

Difficulty making and keeping friends. Trouble understanding social rules and group dynamics. Literal interpretation of language. Advanced knowledge in specific areas paired with gaps in common sense understanding. Sensory sensitivities that affect school participation.

Taking Action

If you recognize several of these signs at any age, request a developmental evaluation. Trust your instincts. You do not need to wait for a specific milestone to be missed. Contact your pediatrician or Treetop ABA Therapy at (855) 800-9361 for guidance.
