Cater for five kiddies with odd breaks (7)
I believe the answer is:
provide
'cater' is the definition.
('provide' can be a synonym of 'cater')
'for five kiddies with odd breaks' is the wordplay.
'for' becomes 'pro' (I've seen this before).
'five' becomes 'v' (roman numeral).
'with odd breaks' means one should take alternating letters (the odd-numbered letters are removed).
The alternate letters of 'kiddies' are 'ide'.
'pro'+'v'+'ide'='PROVIDE'
(Other definitions for provide that I've seen before include "PR video (anag.)" , "'Furnish, supply (7)'" , "Make available, supply" .)
