I’m sorry, that’s very sad. And hard for you all.
There is a good book, called ‘Badger’s parting gifts’ about death and bereavement, which puts things in very accessible terms for kids. Particularly good for the death of a person who has had a long life, but less suitable for an untimely/early death. Another one called The Invisible String’ is a lovely book all about how love is stronger than distance/death. I think in your shoes I would encourage your children to share memories and appreciate the things they have enjoyed in the time you’ve all had together.
Echoing what others have said about giving your children the facts — with anything tricky I tend to answer just the question they ask — resisting the temptation to elaborate, as the elaboration is likely more than they need/can process.
I think it’s helpful to say out loud that someone is dying/has died, rather that they have ‘passed away/moved on/late/departed/gone into another room as this completely confuses a lot of children (and some adults) who then expect them to return.
Also, when it comes to bereavement, many children don’t even begin to process a bereavement (particularly a significant one) until 6months after the event. They may start (as my daughter did) to process themselves at 6months without any warning. Your young one is wrestling with the concept of death/loss at the moment, but they may also come back to think specifically about their grandmother at the 6month point. I know it sounds brutal, but I would be tempted to diary a reminder to check in on my child down the line as after the funeral etc these things get forgotten.
Your school ELSA (as well as class teachers) will be able to advise you and possibly suggest resources along the way. They can keep an eye on your kids in school and I would also remind them at the 6month point too.
When it comes to the funeral, it depends what kind of service you have as to whether it is suitable to take the children. I suggest you see how you feel nearer the time and how the children feel too. If you are involved in planning the service, you can have a lot of say in what you would like to include, even in a church service you can tailor a lot of it. You can discuss it with the celebrant/minister and they might have suggestions. I have been at funerals where the children have written poems and/or memories to be included in the eulogy or in the booklet for the order of service, or included pictures they have drawn of grandparents etc, and helped to choose the music. There is no need to decide on anything now, don’t pressure yourself to decide either way at the moment.
