Girl covering child's bed with cheese (7)
I believe the answer is:
ricotta
'cheese' is the definition.
(ricotta is a type of cheese)
'girl covering child's bed' is the wordplay.
'girl' becomes 'rita' (woman's name).
'covering' indicates putting letters inside.
'child's bed' becomes 'cot' (I've seen this before).
'rita' going around 'cot' is 'RICOTTA'.
'with' acts as a link.
(Other definitions for ricotta that I've seen before include "One soft cheese" , "Italian 8 across" , "cheese, Italian style" , "Italian 4 across" , "Soft white cheese used in Italian cooking" .)
