Which of the following is NOT a sign of meningitis in a baby?

Frequent crying without a reason is not a definitive sign of meningitis in a baby. While excessive or inconsolable crying can be associated with various conditions, it is not specific to meningitis. In this context, the other options are recognized as clinical signs of meningitis due to their specific physiological indicators.

A fever is a common response to infection and suggests an inflammatory process that could be due to meningitis. Very cold hands and feet can indicate poor circulation or shock, which might occur in severe cases of meningitis. Pale and blotchy skin also reflects potential circulatory issues, which can accompany infection-related conditions. Each of these signs can be critical in the early identification of meningitis, making them directly relevant in the assessment of a potentially serious illness in a baby.
