Bullock young kids raised (4)
I believe the answer is:
stot
'bullock' is the definition.
(I've seen this before)
'young kids raised' is the wordplay.
'young kids' becomes 'tots' (I've seen this in another clue).
'raised' shows that the letters should be reversed in order (going up in a down clue).
'tots' back-to-front is 'STOT'.
(Other definitions for stot that I've seen before include "animal on farm" , "walk unsteadily in Glasgow" , "Sort of ox" , "Steer" , "Stupid individual" .)
