Grandma, Gran, Meema and Nana or Grandpa, Gramps, Pawpaw and Pops — there are a variety of traditional or unique names you'll acquire as a grandparent. Many grandparents-to-be try to pick out their own names, but there's also something special about the names grandkids come up with. The kids from different branches of the family might opt for different names, so you might have to get used to responding to a few new names.
