As a psychotherapist, I understand your concerns about your son's behavior. While every child develops at their own pace, there are a few aspects to consider:
Communication Skills: It's positive that your son is engaged with learning videos and has acquired knowledge of shapes, colors, and numbers. However, the fact that he doesn't respond to verbal cues at times, unless prompted with a raised voice, may warrant further observation.
Social Interaction: It's common for toddlers to become absorbed in activities like watching TV or engaging with educational content. However, limited social interaction and failure to initiate communication or ask for basic needs like water could be indicative of challenges in social development.
Sensory Sensitivity: Consider whether your son may have sensory sensitivities that affect his responsiveness to verbal cues. Some children may be more responsive to auditory stimuli when it's heightened, such as a raised voice.
Developmental Milestones: While your son demonstrates knowledge in certain areas, it's essential to assess his overall development across various domains, including social, emotional, and communication skills. Consulting with a pediatrician or child development specialist can help evaluate whether his behavior falls within typical developmental milestones for his age.
Observation and Support: Continue to observe your son's behavior and interactions over time. Encourage opportunities for social engagement and communication in various contexts. Additionally, consider consulting with professionals who specialize in child development if you have ongoing concerns about his progress.
Next Steps
I suggest scheduling an appointment with a pediatrician or child psychologist to conduct a comprehensive evaluation of your son's development. This assessment will help identify any underlying factors contributing to his limited responsiveness and social interaction. Based on the evaluation findings, appropriate interventions and support can be implemented to address his needs and promote healthy development.
