What might be the problem when a newborn baby doesn't cry at all?what procedures must do to the baby?

Newborn crying: Newborns usually cry when hungry or startled or wet, but some babies have a calm temperament and don't cry a lot. Important for the doctor to check the baby's development and neurologic examination.

Depends.: If crying is the only thing absent, and all other factors (turning to sound, breathing, movement, social smile, etc) are present, there may not be anything wrong at all. A good history and physical may be all that's needed.
