I have a step-daughter who is 6. She lives with us full time and calls me mummy. I also have a 6 yo daughter. I really don't like the term "step-daughter" but as the girls are only 4 months apart, I get asked a lot if they are twins. As I can't just say "yes", I feel as though I have to explain our family situation, and that she is my step-daughter.

What do others call their "step-children"?
