I had a little chat with DF yesterday:
Me: Love you! (pause) Do you love daddy?
Me: And mommy?
Me: What about Grandma D?
DF: (big smile on his face) No! She's too famous!
Me: Too famous? What about Nana?
DF: She's too famous too!
Me: What about Grandpa?
Me: And Pop-pop?
DF (another big smile) He's too strange!
He's still trying to figure out language. A little bit later he said 'course' he loves his other grandparents too.
