Carefree child's play (4)

I believe the answer is:

easy

I believe this is a double definition.

'carefree' is the first definition.
(I've seen this in another clue)

'child's play' is the second definition.
(I've seen this in another clue)

(Other definitions for easy that I've seen before include "Men may be told to stand thus" , "Far from hard" , "Relaxed" , "Frederick Marryat's midshipman" , "Comfortable" .)

I've seen this clue in The Telegraph and The Times.
