Take care of doctor who stepped in a puddle (6)
I believe the answer is:
foster
I believe this clue is a double definition.
'take care of' is the first definition.
(as in fostering children)
'doctor who stepped in a puddle' is the second definition.
(as in the nursery rhyme Doctor Foster)
(Other definitions for foster that I've seen before include "support" , "Member of 7 [ORDER OF MERIT]" , "Nurture, bring up" , "Bring up in forest" , "doctor in shower" .)
