here's some ideas that may help.

My daughter's teacher taught her class about visualizing Jesus's garden. It's a beautiful place, you can leave all your worries on the tree if you need too, you can sit on his lap and tell him anything, everything is very safe and beautiful there. If she has a worry she may hang it on the tree and leave it there. Sometimes she does the visualizing and I think it helps her feel like she has something to do with her trouble.

You can tell your child she may come talk to you about anything. Tell her if she talks about troubles it will help her feelings get smaller about it. I give my daughter the option of telling me to "just make it a listening time" if she want and I don't give any advice or opions unless she wants them.

I think it is helpful for children to have goldfish because when they die they can deal with this a little.

There are some children's books that are helpful. Preview to make sure content is right with yor family values. One of the books is called Old turtle. If I recall correctly it talks about a old man being taking care of by his son and lifecycle. Another book, I wish I remembered the name, it is about a grandma who loved to dance and grew to old to dance but then she could do it in heaven and it felt good. These are both picture books. Your librian maybe helpful with options.

There may be parenting resources too.

Maybe your child needs some sort of explanation or reassurance about death because the idea is scarey. It may be good to explain everyone in your family is healthy and you live in a very safe place. I hope this is all true for you.

Try to get her outside for lots of exercise that does alot for everybody. Hope this helps.
