Quite small kid, friend (7)

I believe the answer is:

totally

I'm a little stuck... Click here to teach me more about this clue!

'quite' is the definition.
(thesaurus)

'small kid friend' is the wordplay.
'small kid' becomes 'tot' (tot is a kind of kid. I am not sure about the 'small' bit.**).
'friend' becomes 'ally' (I've seen this before).
'tot'+'ally'='TOTALLY'

Can you help me to learn more?

(Other definitions for totally that I've seen before include "Utterly" , "to the nth degree" , "Clean" , "Absolutely" , "Allowing no exception" .)

I've seen this clue in The Telegraph.
