Repertory company's provision for toddlers? (9)

I believe the answer is:

playgroup

'provision for toddlers?' is the definition.
(toddlers may go to playgroup)

I don't understand how the rest of the clue works.

(Other definitions for playgroup that I've seen before include "Gathering of the very young" , "Where infants may be" , "meeting for parents and children" .)

I've seen this clue in The Times.
