I worry about overstepping my boundaries as a step parent
Well, I bought Eldon cards so the step kids could have fun testing their blood type, too. We did that tonight.
Both the step kids tested AB-. Without thinking, I told my step daughter, "Oh, that means you will have to have special shots when you are pregnant."
After it came out of my mouth, I thought maybe it wasn't my place to tell her that. Oops. :-/
