Son and daughter cuddling brown bear (5)
I believe the answer is:
stand
'bear' is the definition.
(bear can mean to stand or endure)
'son and daughter cuddling brown' is the wordplay.
'son' becomes 's' (genealogical abbreviation for son).
'and' says to put letters next to each other.
'daughter' becomes 'd' (genealogical abbreviation).
'cuddling' indicates putting letters inside (inserted letters are cuddled or held).
'brown' becomes 'tan' (tan is a kind of brown).
's'+'d'='sd'
'sd' placed around 'tan' is 'STAND'.
(Other definitions for stand that I've seen before include "Be likely to rise" , "Remain stationary" , "Seek election; attitude" , "Watch and do nothing to help" , "Be upright; base" .)
