Toddler's break (3)
I believe the answer is:
nap
'toddler's break' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for nap that I've seen before include "Raised fibres on surface of cloth or leather" , "Raised surface of a fabric and short sleep" , "A brief snooze" , "Take forty winks" , "Snatch forty winks" .)
