5 Early Signs of Autism in Babies

15 Apr 2025 | By Emily Parker | 3 min read

Recognizing the early signs of autism is an important step in supporting healthy development in young children. Based on current research and expert guidance—including insights from the Centers for Disease Control and Prevention (CDC)—parents can watch for specific developmental indicators that may signal the need for further evaluation. Identifying these behaviors as early as 6 to 24 months can lead to earlier autism diagnosis, better access to support, and improved long-term outcomes.

Key Takeaways:

  • Lack of eye contact or response to their name by 6 months.
  • Limited facial expressions, such as smiling, by 9 months.
  • Delayed or absent babbling or gestures like pointing by 12 months.
  • Minimal interest in social interactions or playing with others.

1. Lack of Eye Contact

One of the earliest signs of autism in babies is a lack of eye contact. While it’s normal for newborns to have difficulty focusing their eyes, by six months, most babies should be able to make eye contact and maintain it for a few seconds. If your baby seems disinterested in making eye contact, it could be a sign of autism. Learn more about why your baby is staring into space.

2. Delayed Communication

Another early sign of autism in babies is delayed communication. By six months, most babies will start babbling and making sounds, and by one year, they should be saying simple words like “mama” and “dada.” If your baby is not reaching these milestones, it could be a sign of a developmental delay, including autism.

3. Repetitive Behaviors

If you’ve got a baby at home, pay close attention to their actions. While exploring their world is part of growing up, if you notice repetitive behaviors that last for a while – like rocking or hand flapping – it might be more than typical baby play. It’s possible these are autism signs in babies.

Being a parent isn’t easy and spotting signs of autism in babies can be challenging, but it’s crucial. So, if you notice a pattern of repeated behaviors persisting for months, don’t hesitate to reach out to a healthcare professional. Knowing what to look for can make a world of difference in your child’s life.

4. Sensory Sensitivities

Many babies with autism have sensory sensitivities. They may be hypersensitive to certain sounds, textures, or smells, or they may be hypo-sensitive, meaning they seek out sensory input, such as spinning or jumping. If your baby seems uncomfortable or distressed by certain sensory experiences, it could be a sign of autism.

5. Difficulty with Social Interactions

Spotting autism signs in babies can seem daunting, but being informed is critical. When your little munchkin doesn’t seem interested in fun games like peek-a-boo, or they don’t respond when their name is called, it might be a sign they are developing at their own unique pace regarding social skills. It could also be one of the early signs of autism in babies. Remember, we’re all about celebrating individuality and not expecting every child to fit a specific mold. Observing consistent patterns of disinterest or unusual responses in social settings is crucial here. So, to all our Goally parents, keep an eye out, stay upbeat, and embrace the learning journey!

It’s important to know that not all babies with autism show the same signs, and some who show these signs may not have autism. If you have any concerns about your baby’s development, speak with your pediatrician, who can guide you to an early intervention program for further assessment. Early intervention can greatly benefit your child’s growth and help them reach their potential. By staying informed and taking action, you can give your child a strong start in life.
