It was sudden last night. My partner is in bits. I don't know what to do. I will have to tell children when they wake up. I don't know what to say. I don't know whether to keep them home or send to school - for normality. Children 8(severe autism so won't understand), 4 and 2.
I am sorry to hear of your bereavement. Just be there for your DP and just listen to him, hug him, look after him. He may want you to phone his work and explain that he won't be in today. He may or may not want you to help with the funeral arrangements.
For your children, it really depends on whether you have a faith or not. When my parents died my children were adults, so I've not had the experience of telling very young children about a DGP's death.
Take care of yourself as well as looking after everyone else. I would be making soups and food which is comforting and easy to digest and also making sure the home runs smoothly.
