look up any word, like smh:
In our house a diaper change was a "changie". The process of changing a baby's diapers. The proceedure of removing a baby's diapers, be it rubber pants, cloth diapers, and pins, or a disposable diaper, and replacing the wet and soiled diapers with clean fresh ones.

Changie: A diaper change.
As I walked past the open door of the bathroom, a woman could be seen standing next to a baby changing table doing a changie.
