I have three dads. My biological dad, my moms ex husband, and my step dad.

When I was about your eldest daughter's age, my biological dad would take me out maybe once a month and bought me whatever I wanted. All the comic books, all the toys ... he let me do all the things my mom wouldn't allow me to do.

But here's the thing. My moms ex husband and my step dad were the only ones who would go out of their way for me. Kids remember things like that. They also remember family traditions like decorating the Christmas tree or carving pumpkins, going to football games. Who was around during those fun bonding times? Definitely not the biological dad. Who was the one who helped when you felt lost in your new family? Again, not the biological dad.

What I'm trying to say is don't worry. This is a new experience for her and she'll probably want to soak it up for a while. But I think once the novelty wears off, she will be craving the warmth of her real family.
