A small child the editor carried (5)
I believe the answer is:
toted
'carried' is the definition.
(toting is a kind of carrying)
'a small child the editor' is the wordplay.
'a small child' becomes 'tot' (tot can mean a baby or toddler).
'the editor' becomes 'ed' (abbreviation).
'tot'+'ed'='TOTED'
(Other definitions for toted that I've seen before include "Carried (a gun?)" , "Carried (something heavy)" , "Carried - conveyed" , "Bore" , "Lugged" .)
