Could It Be More Than a Phase? A School Psychologist’s Perspective on the Early Signs of Autism

One of the most common questions I hear from parents is whether they should be concerned about their child’s development or simply give it more time. It is an understandable question because childhood is filled with variability. Some children begin talking earlier than others. Some are naturally outgoing, while others are content to observe before joining in. Some develop interests that seem all-consuming for a period of time before moving on to something new. Individual differences are not only expected, they are part of healthy development.

As a licensed school psychologist, one of the most important things I have learned is that evaluating a child is rarely about identifying one behavior or checking off a list of symptoms. Development is far more complex than that. Instead, I look for patterns. How does a child communicate? How do they interact with other people? How do they play? How do they respond to changes in routine? How do they learn from and engage with the world around them? It is the combination of these observations, rather than any one characteristic, that helps determine whether additional evaluation may be appropriate.

One of the first areas I pay close attention to is social communication. Long before children develop sophisticated language, they naturally begin sharing experiences with the adults around them. They point to airplanes flying overhead, look back at a parent after discovering something exciting, smile to share enjoyment, and seek out interactions simply because connecting with another person is rewarding. These moments, known as joint attention, are among the building blocks of social development. When I observe a young child who consistently shows little interest in sharing experiences with others, responds inconsistently to their name, or appears more interested in objects than people, it tells me we should take a closer look at the broader developmental picture.

Language is another important area, but perhaps not in the way many people expect. Parents often focus on the number of words their child is using, and vocabulary certainly matters. However, I am equally interested in how language is being used. Is the child using words to ask for things, or are they also using language to share interests, ask questions, engage in back-and-forth conversations, and connect socially? Some children develop large vocabularies while still finding reciprocal communication difficult. Others may experience delays in expressive language or lose skills they had previously developed. Looking at communication through both a developmental and social lens provides a much clearer understanding than simply counting words.

Play often reveals developmental differences that families may not initially recognize. Most young children naturally begin pretending as they play. They feed dolls, cook imaginary meals, turn cardboard boxes into spaceships, and invent stories that become increasingly creative as they grow. Pretend play reflects important social, language, and cognitive skills. Some children with autism, however, may show less interest in imaginative play and instead prefer repetitive activities, lining up objects, focusing on parts of toys, or engaging with materials in highly predictable ways. These preferences do not automatically indicate Autism Spectrum Disorder, but when they occur alongside other developmental differences, they become meaningful pieces of the overall picture.

Another pattern I pay attention to is flexibility. Most children appreciate routines because they provide predictability and security. The question is not whether a child likes routines, but how they respond when those routines inevitably change. Some children experience significant distress over even small changes in schedules, transitions, or expectations. Others develop intensely focused interests that dominate conversations and play. These behaviors can certainly occur in children without autism, but when they consistently interfere with daily functioning and occur alongside social communication differences, they deserve further exploration.

Sensory experiences also provide valuable information. Some children appear unusually sensitive to everyday sounds, bright lights, certain clothing textures, haircuts, or specific foods. Others actively seek sensory input by spinning, jumping, watching objects move, or repeatedly touching particular textures. Research has shown that sensory processing differences are common among individuals with autism, although they are not exclusive to autism and may also be observed in children with other developmental profiles. Once again, context matters more than any single behavior.

One of the most important messages I share with families is that development should never be viewed through the lens of one isolated characteristic. Toddlers sometimes ignore their names because they are deeply engaged in play. Many children have strong interests. Others become upset when routines change after a long day. Looking at one behavior in isolation rarely tells us very much. What matters is whether multiple patterns emerge across settings, persist over time, and meaningfully affect how a child communicates, learns, plays, or builds relationships.

Parents are often hesitant to seek an evaluation because they worry about what they might hear. I understand that hesitation. However, I also remind families that an evaluation is not about searching for a diagnosis. It is about developing a deeper understanding of how a child experiences the world. Sometimes an evaluation confirms that development is progressing within expected limits and provides reassurance. Other times, it identifies autism, a language disorder, ADHD, developmental delays, or another factor that helps explain a child’s strengths and challenges. Either outcome provides families with something incredibly valuable: clarity.

Research consistently demonstrates that early identification and early intervention are associated with better outcomes for many children with Autism Spectrum Disorder. This does not mean parents should become alarmed every time their toddler develops differently than another child. It does mean that persistent concerns deserve thoughtful attention rather than prolonged uncertainty. Trusting your observations and asking questions is not overreacting. It is part of being an informed and responsive parent.

As a school psychologist, I have the privilege of helping families better understand their children every day. One thing I have learned through those experiences is that a diagnosis never defines a child. Every child brings unique strengths, interests, personality, and potential. The purpose of evaluation is not to place limits on what children can achieve. It is to understand how they learn, communicate, and experience the world so the adults in their lives can provide the support they need to thrive.

If there is one message I hope families take away, it is this: trust your instincts, remain curious, and do not let fear prevent you from seeking answers. Sometimes the greatest gift we can give a child is simply taking the time to better understand who they are.
