She is still young. "Papa" is what she hears him called, or referred to on a regular basis so that is what she thinks his name is, not that he is her father. She knows who that is. Once she is about 5, she will have a better grasp on this because in kindergarten they talk about families.. You should see some of the family trees. My own father has been married 3 times.. Our poor daughter..
When you are speaking with your older daughter do you say, "Tell your Papa, that I need him to call me."? Or do you say, have your Dad call me, Or have "Joe" call me?
What about with your older daughter referring to your fiance? How do you refer to him with your eldest?What does she call him?
When adults in our lives all have multiple names and titles, it can really get confusing for a child.
We have an extensive family. Each time we were going to visit them, my mom would give us the run down. Aunt Sally is my big sister. Uncle, Frank is your dads only brother. Grandma A, is dads Mother.
My husband is still confused about who he is related to and how.. vs, some of his parents best friends, since they spent more time with family friends than their own family.
