Kids tired, only some get out of bed (4)
I believe the answer is:
'get out of bed' is the definition.
'stir' can be an answer for 'get' (thesaurus). I am not certain of the 'out of bed' bit.
'kids tired only some' is the wordplay.
'only some' indicates a hidden word.
'STIR' is hidden within 'kids tired'.
Can you help me to learn more?
(Other definitions for stir that I've seen before include "Big house" , "Bustle, activity" , "Act as an agitator" , "Ado" , "Produce disorder < , wake up" .)
