To spot signs of autism in toddlers, parents should monitor developmental milestones and look for specific red flags in social communication and behavior. Based on CDC guidelines and expert insights, key areas to observe include:

Social and Communication Indicators:

• Lack of response to their name by 12 months.
• Limited or no eye contact and a lack of social smiles by 6 months.
• Delays in language, such as no babbling by 12 months, no single words by 16 months, or no two-word phrases by 24 months.
• Difficulty with joint attention, such as not pointing to share interest or failing to follow a caregiver’s point.

Behavioral and Play Patterns:

• Repetitive movements like hand-flapping, body rocking, or lining up toys.
• A lack of imaginative pretend play or little interest in playing with peers by age 2.
• Unusual or extreme reactions to sensory inputs like sounds, smells, or textures.
• Echolalia, which involves repeating words or phrases without using them creatively.

Practical Home Observations:

• The Name Test: Call your child’s name from 3-5 feet away in different settings to see if they turn or make eye contact.
• Play Check: Observe if the child uses objects in repetitive ways rather than for their intended imaginative purpose.

If you notice these patterns, it is recommended to consult with professionals for a personalized assessment and to explore early intervention services.
