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" .)

I've seen this clue in The Guardian.
