See nothing for a little time in bed (3)
I believe the answer is:
cot
'bed' is the definition.
(cot is a kind of bed)
'see nothing for a little time' is the wordplay.
'see' becomes 'C' (the word for the letter, according to Chambers).
'nothing' becomes 'o' (looks like zero - 0).
'for' is a charade indicator (letters next to each other).
'a little time' becomes 't' (abbreviation for time).
'c'+'o'+'t'='COT'
'in' acts as a link.
(Other definitions for cot that I've seen before include "Small child's bed" , "Small bed with high sides" , "Infant's bed" , "baby carrier?" , "Camp bed" .)
