Carries a kiddie to the rest centre (5)
I believe the answer is:
totes
'carries' is the definition.
(toting is a kind of carrying)
'a kiddie to the rest centre' is the wordplay.
'a kiddie' becomes 'tot' (I've seen this in another clue).
'to the rest' becomes 'rest'.
'centre' says to take the centre.
The centre of 'rest' is 'es'.
'tot'+'es'='TOTES'
(Other definitions for totes that I've seen before include "Carries the betting system" , "Carries or shoulders" , "Bears" , "Carries, lugs" , "Carries, drags" .)
