Distinguishing between a normal developmental variation and a true developmental concern can be tricky. When assessing a child's behavior, what is being observed must be compared to established developmental milestones, such as motor functions, language, social skills, emotional regulation, and cognition. Each child develops at their own pace within expected milestone ranges. I also consider consistency and persistence, context, impact, and regression of a specific behavior to determine where, how, frequency, and loss of acquired skills are affecting daily functioning.
Functional disturbances are a major indicator of whether the behavior interferes with the child's ability to function and participate in daily life. For example, a 3-year-old who's shy around strangers is within normal variation, but a 3-year-old who cannot or will not respond to their name, avoids eye contact, and struggles to engage with caregivers and peers may signal a developmental concern. Another example: it is expected for a 5-year-old to have an occasional tantrum, but a 5-year-old who has repeated, prolonged meltdowns that prevent learning or building relationships suggests a deeper issue. Therefore, some variation in behavior is normal and expected, but when a behavior crosses the threshold into limiting the child's ability to learn, connect, or thrive, that's a key sign it may represent a developmental concern rather than a typical difference.

Use Standardized Assessments for Objective Evaluation
Well, using standardized assessment measures is the most effective way to objectively evaluate development. Psychological measures that are normed for use with children, and have standard comparison groups with scores, are my go-to. We look for statistically and clinically significant delays, or atypical development such as autism. Autism is not just being behind in development compared to same-age peers, but also showing some differences or atypicality in development.

Track Progress Across Multiple Developmental Areas
Child development follows a general pattern, but consistent delays across multiple areas can be a red flag. These delays might appear in language, motor skills, cognitive abilities, and social interactions. While all children develop at their own pace, falling significantly behind in several areas could indicate a deeper issue. It's crucial to track a child's progress in various developmental domains over time.
Parents and caregivers should keep a record of milestones and discuss any concerns with a pediatrician. Early identification of potential problems can lead to timely interventions and support. Don't hesitate to seek professional advice if multiple developmental areas seem consistently delayed.
Watch for Persistent Loss of Skills
The loss or regression of previously acquired skills in children can be a cause for concern. This might involve a child who was speaking in short sentences suddenly using only single words or not talking at all. It could also manifest as forgetting how to perform tasks they once mastered, like using utensils or getting dressed. While temporary regressions can occur during times of stress, persistent loss of skills warrants attention.
Parents should note when and how often these regressions happen. It's important to rule out medical causes and consider environmental factors that might be affecting the child. If skill loss persists, consult with a developmental specialist to determine the best course of action.
Observe Social Communication and Interaction Abilities
Social communication and interaction form the foundation of human relationships. When a child shows significant and persistent difficulties in these areas, it may indicate a developmental concern. This could manifest as trouble making eye contact, difficulty understanding social cues, or challenges in forming friendships. Some children might prefer solitary play and struggle to engage in imaginative or cooperative activities with peers.
These difficulties can impact a child's ability to learn and thrive in social settings. Observing how a child interacts in various social situations can provide valuable insights. If social challenges persist, consider seeking guidance from a child psychologist or speech-language therapist to develop strategies for improving social skills.
Assess Responses to Sensory Input
Sensory processing involves how the brain receives and responds to information from our senses. Some children may have persistent challenges in this area, showing unusual responses to sensory input. This could include being overly sensitive to certain sounds, textures, or lights, or seeking out intense sensory experiences. A child might become overwhelmed in noisy environments or have extreme reactions to certain clothing textures.
These sensory issues can affect daily activities, learning, and social interactions. It's important to distinguish between typical sensory preferences and more significant processing challenges. Creating a sensory-friendly environment can help, but if difficulties persist, consult with an occupational therapist who specializes in sensory integration for professional guidance.
Evaluate Adaptability to New Situations
Adapting to new situations is a crucial skill for children as they grow and face various life changes. When a child consistently shows extreme difficulty adjusting to new environments, routines, or people, it may signal a developmental concern. This could manifest as severe anxiety, tantrums, or complete withdrawal when faced with changes. While some hesitation is normal, persistent and intense reactions can hinder a child's ability to learn and socialize effectively.
Parents and caregivers should observe how the child responds to different types of changes and transitions. Gradually exposing children to new experiences in a supportive manner can help build adaptability. If a child's struggles with change significantly impact daily life, consider consulting a child psychologist for strategies to improve flexibility and coping skills.
