My 9yo has told me he keeps thinking about death/dying and can't get it out of his head. It's been going on over a month now. It's usually at bedtime but today he said he'd been thinking about it during the day. It upsets him when he can't stop his brain doing it. I've tried talking to him about it, asked him if he has any questions, I've talked about how it's a natural process and all animals and humans die etc. I've talked about how some people believe in heaven and others have other religious beliefs. We're not religious so maybe it makes it harder for him. I've also told him to distract himself with reading or thinking about other things but he says it doesn't work. I'm just not sure what to do. I've googled and advice just says they'll 'grow out of it' -really helpful!
TIA!
