In evaluating a child’s development, which concern would be considered most severe?

The concern regarding a child not walking is considered the most severe in terms of developmental evaluation. Walking is a significant milestone in gross motor development and typically occurs anywhere between 9 to 15 months of age. If a child has not begun to walk by 15 months, it could indicate potential developmental delays or underlying health issues that may require further assessment.

If a child does not walk, it may also impact their overall mobility, independence, and ability to interact with their environment, which can further affect social and emotional development. Early intervention is crucial in cases of developmental delays, as addressing issues early on can lead to better outcomes.

The other options, while they might raise concerns about development or health, do not typically indicate a direct developmental milestone that is as critical as walking. For instance, using a bouncy walker or watching television, while potentially problematic in terms of safety or screen time guidelines, does not have the same direct impact on a child's ability to move independently. Similarly, both parents working outside the home may concern some regarding a child’s socialization and attachment, but it is less directly related to critical physical milestones.
