Wikipedia defines a helicopter parent (also called a cosseting parent or simply a cosseter) as a parent who pays extremely close attention to a child’s or children’s experiences and problems, particularly at educational institutions. Paying close attention would be admirable if parents were insisting their children complete homework assignments, behave appropriately, and learn how to deal positively with failure and gracefully with success. But this isn’t what helicopter parents are doing. Instead, they’re insisting their children receive good grades without earning them and receive special accommodations without needing them.
