DS (5 years) calls DP (not his bio-dad)'s parents by their first names. He also calls them "Jason's mom" and "Jason's dad". My parents are Grandma and Grandpa. Ds's bio-dad's parents are "Grandma first name" and "Grandpa first name", though that almost never comes up in conversation. DS's bio dad is just called by his first name. DP is called by his first name, though if you ask ds who his dad is he'll tell you dp's name.

We like to be complicated
