Little boy who runs nimbly (6)

I believe the answer is:

nipper

I believe this clue is a double definition.

'little boy' is the first definition.
(I've seen this before)

'who runs nimbly' is the second definition.
(someone who nips around)

(Other definitions for nipper that I've seen before include "Child (slang); one that 19s" , "One pinches" , "Little kid" , "one given to pinching things" , "A pincer or a young boy" .)

I've seen this clue in The Times.
