Child framing answer perfectly (2,1,1)
I believe the answer is:
to a t
'perfectly' is the definition.
(I've seen this before)
'child framing answer' is the subsidiary indication.
'child' becomes 'tot' (tot is a kind of child).
'framing' is an insertion indicator.
'answer' becomes 'a' (abbreviation e.g. in Q&A).
'tot' going around 'a' is 'toat'.
(Other definitions for to a t that I've seen before include "In every detail" , "Exactly right" , "perfectly well" .)
