My child isn’t responding to my commands right away. They aren’t playing with the other kids or singing Frozen songs. My child cuts his sandwiches straight down the middle instead of diagonally! Does my child have autism? Woah woah woah, ease up there. It’s good that you are concerned about your child’s development, but let’s take a step back. It’s unlikely that your child has autism. Autism is much more likely to be first noticed when your child is in school. Learn more about the signs of autism below!

5 Signs of Autism

1. Sensitivity to Background Noise

Although all children may exhibit negative reactions to loud sounds, children with autism have a particularly strong aversion to loud noises. This may cause them to react by grimacing or wincing, rather than showing surprise or a normal wide-eyed curiosity. Signs of autism may be if you see your child convey their strongest emotions in the form of an adverse reaction to the music or TV being turned up too loud… or if adults in the room are having a loud and animated conversation… or even when you run the vacuum cleaner. Children with autism process the world around them differently. They may have trouble filtering out background sounds coming from the microwave or washing machine; sounds that would disappear as white noise for neurotypical children. These reactions may result in fits, crying, anger, or even physically aggressive behavior.

2. Difficulty Recognizing Facial Expressions and Keeping Eye Contact

Early on children learn to make eye contact with their parents, smile when they are being smiled at, and point or wave at things they find interesting. Children on the autism spectrum have a harder time recognizing emotion in facial expressions and may show little to no emotion themselves. For example, if something falls off the counter it’s normal for a child to look at their parents and process their facial expression to see what the reaction is. This is done as a way to verify if they too need to be concerned with what just happened. However, signs of autism would be a child having no reaction at all, which for a parent, can be very puzzling and concerning. Because children on the spectrum have trouble reading facial expressions, they may fail to react when a parent or sibling expresses joy, anger, or sorrow.

3. Speech and Language Difficulties

Children with autism may struggle to communicate and speak at the same level as their peers of the same age. In fact, even during infancy, you may notice that your child isn’t cooing in response to your attempts to interact and communicate. Typically, by the time a child reaches their first birthday, they’re able to speak a word or two. However, children who are on the autism spectrum may not develop their speaking abilities until later in life. Interestingly, some children with autism do coo during their first few months of life, but then suddenly stop communicating altogether. In these cases, all forms of verbal communication and typical language development abruptly come to a halt.

This can be disconcerting for parents. Often it’s a sign that it’s time to investigate further by seeking professional help. Sometimes children with autism do speak and demonstrate pretty typical signs of normal language development, they often repeat unrelated words and phrases over and over and, in essence, speak without really communicating or conveying a feeling, thought or desire. Early intervention is key to helping your child learn to communicate, whether it’s through spoken language or even through sign language if necessary. 

4. No Interest in Interacting With the World

For the neurotypical child, the world is full of bizarre and wonderful things that they have never seen or encountered before; things that naturally interest and draw them in. The normal response to a new experience or discovery is typically wide-eyed excitement. Children with autism respond to the world very differently. You might notice that your child doesn’t really respond with eye contact or normal outward signs of curiosity when you try to get their attention. They might not even turn their head in your direction when you say their name. Signs of autism might be them not pointing at objects, showing a normal level of curiosity, or attempting to engage with you.

A lack of responsiveness to stimuli and a lack of interest in trying to seek parental attention is a pretty common sign that a child may fall somewhere on the spectrum. Children typically learn through imitation. Even at an early age, the neurotypical child will begin copying adult behaviors, like them pretending to cook, holding an object up to their ear as if they are talking on the phone, or pretending to feed and care for a doll.

5. Sensory Stimuli Results in Overreaction or No Reaction

Many people with autism have trouble processing sensory information and can become easily overwhelmed. Sights, sounds and movements, even tastes and smells, can all be overwhelming to a child with autism. You may notice either an observable overreaction or an under-reaction to stimuli. In the case of an overreaction, they may avoid touch. I could be something as gentle like a pat on the head or a touch on the arm. Others may throw a fit when getting dressed because the sensation of the clothing creates a feeling of anxiety.

If your child has autism, they may exhibit signs of hypersensitivity to noise and other stimuli. For instance, your child may not respond to sounds that would usually startle or surprise other children. This can be so unusual that you might begin to wonder if your child is experiencing hearing problems. It’s normal for children to have a strong negative reaction to new and overwhelming things. However, if your child doesn’t react at all, that can be concerning. For example, if you take your child to the circus for the first time and they don’t respond to the clown by either laughing or freaking out, it could be a red flag that your child needs further evaluation.

By being aware of common indicators such as social communication challenges, repetitive behaviors, sensory sensitivities, and delayed language development, parents and caregivers can seek professional guidance and resources to help their child thrive. It is important to remember that every child is unique, and autism presents differently in each individual. Seeking a professional evaluation is the first step towards understanding and supporting children with autism, fostering their development, and providing them with the tools they need to navigate the world successfully. With early identification and appropriate interventions, children with autism can reach their full potential and lead fulfilling lives.
