Faster cuddles providing comfort for child (8)
I believe the answer is:
pacifier
'comfort for child' is the definition.
(US term for a child's dummy)
'faster cuddles providing' is the wordplay.
'faster' becomes 'pacier' (pacy can mean fast).
'cuddles' means one lot of letters goes inside another.
'providing' becomes 'if' (eg 'providing it's sunny' means 'if it's sunny').
'pacier' enclosing 'if' is 'PACIFIER'.
(Other definitions for pacifier that I've seen before include "Peacemaker" , "Baby's dummy" , "One soothing; US dummy" .)
