Sleep disturbances due to grief

[KTD27]

Hi all
Not sure this is in the right topic but hoping for some tips.
A week ago my FIL died. It was a total shock and happened in front of my 4 year old. Just horribly traumatic and awful.
For the most part, he’s doing ok. Lots of questions but generally ok.
However sleep is an issue. He’s always been a great sleeper - down for the night happily and sleeps right through until morning. Since last week he’s been up and down after settling for the night. He’s said tonight he’s afraid of the dark.
Do you have any tips to help get through this tough bit?
I don’t know how to reassure and I’m worried I’ll do the wrong thing.

Hi, How is it going now? I don't have much experience with anything like this but perhaps a night light/music box could help? Or a special teddy bear to help him to sleep? Although I would just be there for him while he needs the extra reassurance as this is hopefully temporary and he just needs some reassurance and extra cuddles (which I'm sure you're giving him).

Ah thank you so much for commenting. We are doing ok. I contacted winstons wish who were super super helpful and got a recommendation of a few books - some id ordered already and some I hadn’t heard of. They’ve helped massively. As did a nightlight and a worry bear which someone suggested on here.
He’s doing much much better thank you
