One day he was going on about Kiki, how she does things in a certain way and I kept him going by say how interesting it was. He then turned to me and asked “You know that Kiki isn’t real, right, I made her up?”. He doesn’t like lying or being lied to, so within that frame I guess he wanted me to confirm that it was just play.
Our child has one. Her name is Kiki and she lives on a farm where she drives her tractors in a village called Plamplams. She speaks also an imaginary language. It seems like she represents experience he lives through vicariously expressing some image he has on how he fits in this world. We as his parents have always encouraged him; it is wonderful how he develops such creative images.
What other posters said, respond with the blinking. My son calls them eye kisses. It shows trust. In case you’re unfamiliar: you look at her and slowly close your eyes for a second. She might mirror it. Facing a fierce predator such as the one you pictured and confronting it willingly blinded, even for a second, takes courage. She’ll honour it most likely. Also food and clean water, preferably placed in separate locations.
