Towards the end, accepting work to feed the kids? (7)
I believe the answer is:
lactate
'feed the kids?' is the definition.
(breastfeed children)
'towards the end accepting work' is the wordplay.
'towards the end' becomes 'late' (I've seen this in other clues).
'accepting' indicates putting letters inside (inserted letters are accepted).
'work' becomes 'act' (synonyms).
'late' enclosing 'act' is 'LACTATE'.
'to' is the link.
(Other definitions for lactate that I've seen before include "Produce milk" , "Exude milk" , "(Of female mammal) secrete milk" .)
