Child’s enclosure (7)
I believe the answer is:
playpen
'child's enclosure' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for playpen that I've seen before include "Portable enclosure for young-child" , "Limited room for amusement" , "juvenile restraint" , "Toddler's enclosure" , "Enclosure for child" .)
