Autism spectrum disorder is often suspected when young children stand out as being different from their peers. That can be much harder in this isolated time

We talk often in pediatrics about the importance of early identification and early treatment of autism spectrum disorder, with its hallmark issues of social communication problems and restricted repetitive behavior patterns. “Early” means paying particularly close attention to the behavior and development of children between ages 1 and 3, and checking in with their parents about any concerns.

But what does that mean for young children who have now spent half their lives — or more — in the special circumstances of the pandemic?

Dr. Heidi Feldman, a professor of developmental and behavioral pediatrics at Stanford University School of Medicine, said, “We don’t know what the impact of one year of very restricted social interaction is going to be on children.” Some of the behavior patterns that children are showing now may be the result of these strange living conditions, or they may reflect stress, trauma and the social isolation that many families have experienced, she said.

Dr. Feldman said that first-time parents who have been operating in the increased isolation of the pandemic may have very limited context for appreciating where their child’s behavior falls. They’re missing the input they might usually get from teachers and child care providers.

Dr. Eileen Costello, a clinical professor of pediatrics at Boston University School of Medicine and chief of ambulatory pediatrics at Boston Medical Center, said, “Especially for the really little ones, the only eyes that are on them are their parents’. They’re not seeing uncles and aunts and cousins, not in preschool.”

Dr. Costello and I are co-authors of the book “Quirky Kids: Understanding and Supporting Your Child With Developmental Differences.” We use the word “quirky” to encompass children whose development does not follow standard patterns, whether or not they fit the criteria for a specific diagnosis. Some of these children will accumulate several different diagnoses as they grow and change — and as different demands are made on them in terms of academic performance and social life — and others will never fit the criteria for any specific formal diagnosis.
