Identifying potential signs of autism in toddlers involves monitoring developmental milestones and social behaviors. According to CDC guidelines and expert insights from Heart Core ABA, parents should look for several key indicators across different areas of development.

Communication and Social Red Flags:

• Not responding to their name by 12 months of age.
• Limited or no eye contact during interactions.
• Lack of social smiling or not sharing smiles with caregivers.
• No babbling or gesturing (like pointing or waving) by 12 to 16 months.
• No single words by 16 months or spontaneous two-word phrases by 24 months.
• Difficulty with joint attention, such as not following a caregiver’s point or not showing objects to others.

Behavioral and Play Indicators:

• Repetitive movements, including hand-flapping, body rocking, or spinning objects.
• Lining up toys in perfect rows and becoming distressed if they are moved.
• Lack of imaginative or pretend play by age 2, such as using a block as a phone.
• Echolalia, which is the repetition of words or phrases rather than using original language.
• Intense focus on specific objects or preferring to play alone rather than with peers.

Sensory and Motor Signs:

• Unusual or extreme reactions to sounds, smells, lights, or textures.
• Motor patterns such as toe-walking or difficulties with 1balance and coordination.
• Delayed motor milestones like crawling or walking.

If these signs are observed, professional consultation for early intervention and personalized assessments is recommended to support the child’s communication and independence.
