Family and nicknames

sthomas1222

How do you handle grandparents-to-be who insist on using a nickname that you absolutely hate. We're naming DD Addison Grace and intend on calling her Addy. My dad keeps calling her Gracie, which to me sounds like a cat or a grandma or some combination there of. I've told him soooo many times to call her anything else but please don't use that name. I absolutely hate it. Now it's getting to the point where I just want to smack him whenever he says it. His response is "I'm grandpa, I can call her whatever I want." Uh no, I'm sorry but no.
