Any cute name suggestions for Grandma?

Hi ladies! My mom is having a tough time choosing her name to be called by our baby boy! He will be the first grand baby! I know kids tend to call you what they want, but wondering if you had any cute suggestions to start her off!! Ps:: she doesn't want "Glamma," and my mother in law is already "Gi-gi." She also doesn't want grandma or Grammy or Meemaw.... (Picky lady lol) Thank you!! 💖
