Direct familiar child's play (15)

I believe the answer is:

straightforward

'child's play' is the definition.
(both can mean very easy)

'direct familiar' is the wordplay.
'direct' becomes 'straight' (similar in meaning).
'familiar' becomes 'forward' (similar in meaning).
'straight'+'forward'='STRAIGHTFORWARD'

(Other definitions for straightforward that I've seen before include "Right on!" , "That's simple" , "Uncomplicated" , "Elementary" , "Honest, open" .)

I've seen this clue in The Independent.
