Who do you love more?

Had this pillow talk with Ian last night.

Me: Do you love daddy?
Ian: Yes.
Me: Do you love mommy?
Ian: Yes.
Me: Who do you love more? mommy or daddy?
Ian: Mommy and daddy.
Me: No.... choose one only. Mommy or daddy?
Ian: Mommy and daddy.
Me: Do you know what is choose one only?
Ian: Mommy (paused).............. and daddy.
Me: (decided not to push my luck.) Good. Both mommy and daddy love you too.

I know it is not healthy to have this conversation to make him choose one. Curious lah. Just wanna see what goes on in his little mind.
