Copy child's bed (4)
I believe the answer is:
crib
I believe this is a double definition.
'copy' is the first definition.
(crib can mean to copy from another source)
'child's bed' is the second definition.
(bed for a baby or young child)
(Other definitions for crib that I've seen before include "Nativity scene; copy illicitly" , "Baby bed with high sides" , "Cot - copy another's work" , "Steal the work" , "Cot; translation cheat" .)
