Bog lands may not work with animals and children (1,1,6)

'animals and children' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'bog lands may not work' is the wordplay.
I cannot quite see how this works, but
'lands' could be 'fields' (field is a kind of land) and 'fields' is found in the answer.
'work' could be 'w' (physics abbreviation) and 'w' is present in the answer.
A single letter 'c' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...

'with' acts as a link.

Can you help me to learn more?
