Walk like a young child (6)
I believe the answer is:
toddle
'walk like a young child' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for toddle that I've seen before include "Walk like baby" , "Walk unsteadily like a small child" , "Aimless stroll" , "Walk like a young child" , "Walk uncertainly like infant" .)
