My three step-kids all call me "Mom" or "Mommy," which I love and their bio-mother is OK with. (Don't even get me started, because I would freak the hell out if my kids called another woman Mom, but whatever... not what this post is about.) I love these kids like my own and they can call me whatever they want.
In conversations with other people, I hate referring to them as my step-kids, but it's confusing to just say mine when all of our kids' ages (I have two) overlap.
Does anyone else have creative alternative names to replace "step" when referring to your blended family?
