How should I prepare my child for surgery/anesthesia?

Children of all ages need to be reassured that someone will be with them
at all times. In addition, careful choice of words is important; for example,
let your child know that medicine will be given immediately if they feel
"sore" after surgery, not that they may have "pain."  Similarly, when
explaining the surgery, use the phrase "make an opening" instead of "cut."
Encourage your child to ask any questions they may have at any time prior
to the procedure. If necessary, write them down so they can be
answered later.
