Hell! Some baby’s screaming! (5)
I believe the answer is:
abyss
'hell' is the definition.
(I've seen this before)
'some baby's screaming' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'ABYSS' is hidden within 'babys screaming'.
(Other definitions for abyss that I've seen before include "Bottomless gulf" , "Bottomless pit" , "Fathomless pit" , "gaping hole" , "depths of sea" .)
