Persistent irritability despite feeding or inability of parents to console the child is concerning. True irritability and lethargy are physical signs traditionally associated with an ill child. Lethargy is defined as a decrease in the level of consciousness, some examples of which are failure of the child to recognize parents or caregivers, absent eye contact with the examiner, or failure to interact with the environment at an age-appropriate level.
