Do as I do facing queen: that's child's play! (6-2-6)

I believe the answer is:

follow-my-leader

'child's play' is the definition.

'do as i do facing queen' is the wordplay.
'do as i do' becomes 'follow my lead'.
'facing' says to put letters next to each other.
'queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'followmylead'+'er'='FOLLOW-MY-LEADER'

'that's' is the link.

(Another definition for follow-my-leader that I've seen is " Mimicking game".)

I've seen this clue in The Telegraph.
