Child embraces press operator (7)
I believe the answer is:
surgeon
'operator' is the definition.
(someone who operates)
'child embraces press' is the wordplay.
'child' becomes 'son' (male child).
'embraces' means one lot of letters goes inside another.
'press' becomes 'urge' (press can mean to urge or encourage).
'son' placed around 'urge' is 'SURGEON'.
(Other definitions for surgeon that I've seen before include "Medical man" , "Naval medic" , "One who operates" , "incisive person" , "Theatre worker" .)
