Bit of luck in the parental bed (6)
I believe the answer is:
mascot
'bit of luck' is the definition.
'mascot' can be an answer for 'luck' (thesaurus). I am not certain of the 'bit of' bit.
'parental bed' is the wordplay.
'parental' becomes 'mas' (I can't explain this - if you can you should believe this answer much more).
'bed' becomes 'cot' (cot is a type of bed).
'mas'+'cot'='MASCOT'
'in the' is the link.
Can you help me to learn more?
(Other definitions for mascot that I've seen before include "It's adopted by a team as a symbolic figure" , "Team's good-luck bringer" , "Lucky talisman" , "that's charming?" , "Good-luck charm" .)
