Pediatricians
are doctors who specialize in diagnosing, treating, and preventing disorders
and diseases in children. This type of profession is a branch in medicine that
still aims to focus on the same principles that other doctors have in their
practice, except that the age of patients vary. They manage the physical,
behavioral, and mental health of children the moment they were born up to the
age of 21. They are well trained to diagnose a variety of minor and major
diseases in children and identify noticeable traits that younger children
cannot directly express through speaking.
