Help with 5 year old..

Hi girls, so my 5 year old little girl is really worried. Her friend at school told her a few weeks back that her brother died when he was younger because he eat soap. I dont know what the story is or what happened.. weather he checked or what.. or even if its actually true.

Since this.. my little girls swallowed a coin.. she was meant to be in bed, came running downstairs crying and screaming saying she was going to die..

I reassured her.. calmed her down.. went to a&e the next day and all was fine..

She has a little cut or scratch and goes over the top with it..

Theres been a few conversations along the way where shes brought death up..

Tonight while brushing her teeth.. she licked the sideboard 😏🤨

Shes come running back downstairs saying she licked the sideboard and it tasted like soap..

It wasnt soap it was toothpaste!

I've again reassured her that she is going to be okay but she keeps freaking out saying her friends little brother died from eating soap..

I'm really stuck on what to do.

I have a y year old boy who has never been through this stage of thinking about death and finding it hard to reassure her when shes only 5.

Has anyone been through this?
