Firstly, I'm very sorry about your health and I hope you have as much time left here as is needed to fulfill what you want to do for your children before going on to the next life.
I like Dowser's idea whereby "Just before my mum went into a care home with dementia in 2012 I started to write the book of my life so my grandchildren knew their roots and the lovely families they came from"
When my dad died 9 years ago I started to have the most stupid questions like:
- What colour was his childhood bike? (I knew he used to take it apart and put it back together again in the back garden so he could be close to his dad whilst he was doing the garden).
- Which of his sets of grandparents he preferred.
- Ths primary school he went to (his childhood home was over 200 miles away).
His writing was beautiful and he'd sent me plenty of notes over the years. Even if he went away for couple of days he would send a post card to me and I have one which, uncharacteristically, says on it "PS I love you" which is now a treasured possession. I've always, thankfully, kept all greeting cards from close family. Having his writing means such a lot to me.
Recipes is also a great idea. DC always think no-one ever makes meals as good as your mum.
I used to be bored by Family History and couldn't understand why anyone would want to trace their ancestry. However, I started this before my dad became ill and he just wrote me some information about his family which really helped me find where my ancestors lived. It also left me with great feelings about him as his personalty shone through from things he wrote about each.
On the subject of videos I would suggest you don't wait until much later on as you, presumably, want your DC to remember you looking as healthy as possible.
After hmy dad died I wrote reams of stuff such as his favourite TV programmes over the years, his favourite songs, colours, clothing and lots of my memories from over the years. Perhaps you could do that for your chidren to make sure, in years to come, they don't forget these things which seem really trivial now but aren't.
I also love the Christmas bauble idea and, in fact, I buy my dad a bauble each year and put it on a Christmas tree that we take to the Gardens of Remembrance. It's a new tradition we have for him.
Maybe each child could have a mini Christmas tree that you buy and decorate for them that they keep forever so that each Christmas they look at it and remember you.
