Young children in shorts (4)
I believe the answer is:
tots
This could be a double definition.
'young' is the first definition.
(thesaurus)
'children in shorts' is the second definition.
'tots' can be an answer for 'children' (tot is a kind of child). I'm not certain of the 'in shorts' bit.
Can you help me to learn more?
(Other definitions for tots that I've seen before include "Babies" , "Little children" , "Party drinks" , "Little drinks" , "Sailors' drams" .)
