I'm expecting my first and planning to announce to my family over Thanksgiving, and I'm sure everyone is going to be thrilled. One of the things I'm worried about though is how to handle a name for my Dad's second wife. It's the first grandkid on my side, so there's nothing established. My mother has passed so there's no risk of tension there, but I'm not sure I'm comfortable with her being Grandma either. I've thought about Grandma Debbie or Didi, and DH looked up Polish terms for Grandma and found Baba or Babcia (she's of Polish heritage) but I'm wondering what other people do. If you have step parents what do your kids call them?
