A mum I know of has died leaving three dc. What can we do to help the dh and children?

[VanillaPumpkin]

Are there any books / support networks you would recommend that I could pass on to the dad to help him and especially the children?
We all feel utterly useless. I did not know the family well, but have to do something . Any advice gratefully received. TIA.

And are grateful

Thank you for the comments and extra advice. Glad the Mum's mafia gets a thumbs up .
