Common Signs of Autism in Babies: 0-6 Months

Autism signs in babies from 0 to 6 months can be subtle. Yet, it’s key to spot these early signs for early help. During this time, babies start showing behaviors that help with their social and emotional growth.
Early Social Engagement Warning Signs
Watching how babies interact is important. Those with autism might not show many facial expressions. They might also not follow moving things with their eyes.
They could be very sensitive to loud sounds. This could be a sign of a developmental problem.
Another warning sign is avoiding eye contact. Babies usually start making eye contact from birth. This is a key part of their social growth. If they avoid or don’t make much eye contact, it could mean they might have autism.
Response to Caregivers vs. Strangers
By 0 to 6 months, babies start to know the difference between their caregivers and strangers. Babies with autism might find it hard to tell the difference. This can show as being too friendly to strangers or not wanting comfort from their caregivers.
Seeing how your baby acts with you versus a stranger is telling. Usually, babies are more into their primary caregivers. If your baby acts differently, like being too friendly to strangers or not wanting comfort from you, talk to your pediatrician about it.
Knowing these early signs helps parents get help early. This can lead to important interventions that can really help a child grow.
Key Indicators of Autism in Babies: 6-12 Months
Babies grow a lot from 6 to 12 months. They start showing signs that help us see if they might have autism. During this time, they begin to show important skills for talking and socializing.
Communication and Language Development
By 6 months, babies start making sounds to talk. By 9 to 12 months, they try to imitate sounds and say their first words. Babies with autism might not make sounds or try to talk as expected.
Look for signs like not babbling, not responding to their name, and not using gestures like waving. A study by the Kennedy Krieger Institute says signs in older babies include not crawling, avoiding eye contact, and limited or hard-to-understand speech.

Joint Attention and Pointing Gestures
Joint attention is when a child looks at something and shares it with someone else. Pointing is a big milestone that comes around 9 to 12 months. Babies with autism might struggle with these and not use pointing to talk.
Name Response and Social Imitation
Responding to their name is a big social clue. By 9 months, babies should turn to their name. Babies with autism might not always respond to their name. They might also not imitate facial expressions or gestures well.
Here’s a quick summary of the key signs:
| Developmental Area | Typical Development | Possible Autism Signs |
| Communication | Babbling, making sounds, first words | Limited or no babbling, not using gestures |
| Joint Attention | Sharing focus with others, pointing | Difficulty with joint attention, not pointing |
| Name Response | Responding to name by 9 months | Not consistently responding to name |
| Social Imitation | Mimicking expressions and gestures | Differences in social imitation |
Knowing these signs can help spot delays early. If you’re worried about your baby’s development, talk to a doctor.
