DD neally 5 has been mentioning dying of late aswell, but more on the lines of her laying down saying she is dead. We havent had any close relatives pass away so not sure where it is coming from maybe daycare. I often just say that I would miss her terribly if she was dead and would be sad for a long long time. She then just tells me that she is just pretending and she gives me a hug. I would be alittle more worried if E knew the process of how to die at 5 and threatened it to me.
Good Luck hopefully it is a phase
