So, what kind of stepgrandparent are you? You might not be one but the odds are someone in your family will be. There are three kinds: long-term stepgrandparents raised a stepchild and then became a grandparent when their stepchild had a kid. Inherited stepgrandparents inherited grandchildren when their adult son or daughter became a stepparent. And later-life stepgrandparents married a grandparent and instantly got stepgrandchildren. No matter what, it’s up to all three generations to act in loving ways and build a relationship.
