A book about death for my dc..l

[Badvoc]

Does anyone know of a book that can help children understand about death...particularly sudden and unexpected death?
We lost my beloved dad on 27th July and I am not sure that mine and Dhs explanation (that his heart stopped and he died straight away) makes any sense to them.
Ds1 is 10 and ds2 is 4.
Thanks

Thanks polter x

Grandma's Gloves by Cecil Castalucci deals with the subject in a sensitieve and touching way, My 4 year old dd read it recently.

I think an older child might get more out of it though.
