Avoided lad on bed with cuddly toy (9)
I believe the answer is:
boycotted
'avoided' is the definition.
(to boycott is to avoid or refuse to use)
'lad on bed with cuddly toy' is the wordplay.
'lad' becomes 'boy' (I've seen this before).
'on' says to put letters next to each other (in a down clue, letters appear on others).
'bed' becomes 'cot' (cot is a type of bed).
'with' is a charade indicator (letters next to each other).
'cuddly toy' becomes 'ted' (short for teddy bear).
'boy'+'cot'+'ted'='BOYCOTTED'
(Other definitions for boycotted that I've seen before include "Shunned (something) in protest" , "Ostracised by octet body" .)
