Maybe a little bit like little tiny roommates, or pets. I talk to them a lot. I take pictures of them. I do stuff with them when I am around the house. I tend to pat them on the heads if I walk past one that catches my attention, or even stop to say something to the doll. If I don't give them attention I feel a little guilty about it. I know they are dolls but I treat them a little bit more like people over say, how I would treat a chair. Although if I bump into a chair, I might also say excuse me.
I acknowledge them as inanimate objects, but I also project personalities onto them. Like little friends whose lives I control >
