Kid's newspaper (3)
I believe the answer is:
rag
I believe this is a double definition.
'kid's' is the first definition.
(both can mean to tease)
'newspaper' is the second definition.
(informal term for a newspaper)
(Other definitions for rag that I've seen before include "Practical joke" , "Mock < paper that's poor" , "slate" , "Torn piece of cloth or university japes" , "Scrap -student carnival" .)
