Every baby develops independently, but some early behaviors might indicate autism. Recognizing these signs early can help parents and caregivers provide the right support. While autism is usually diagnosed later in childhood, subtle indicators can appear in infancy.
Early Social and Communication Signs
One of the first differences parents notice is how their baby interacts with people. Some early social and communication signs of autism include:
Limited Eye Contact – A baby may not make or maintain eye contact, even during feeding or play.
Lack of Social Smiling – Babies typically begin to smile back at caregivers around 6–8 weeks old. A lack of response may be an early sign.
Delayed or Absent Babbling – By 6 months, most babies make cooing or babbling sounds. Babies with autism may be quieter or not respond to sounds.
Not Responding to Their Name – By 9 months, babies usually turn their heads when their name is called. A lack of response could indicate a difference in communication development.
Sensory and Behavioral Indicators
Autistic babies might experience the world differently due to heightened or reduced sensory processing. Some possible signs include:
Unusual Reactions to Sounds or Textures – Some babies may not react to loud noises, while others may be startled easily.
Repetitive Movements – Flapping hands, rocking, or staring at objects for long periods may be early repetitive behaviors.
Preference for Objects Over People – A baby may focus more on objects than faces or interactions.
What to Do Next
If you notice any of these signs, asking questions is okay. Speak with your pediatrician and track developmental milestones. Early support, whether through speech therapy or sensory integration strategies, can help your child thrive. Every baby is unique, and early awareness leads to better understanding and support!
