Thanks everybody for being so understanding and sympathetic.
The poems are lovely and I have had a look at the other links.
For the moment the sundial idea seems the best to me. I would like to write her wee poem, but so far nothing suitable has come out.
It's only been a few days, but I already know , that, yes, it was worth having her with me all those years, although it hurts to know she's gone.
Luckily I have her mum and her sister, and they are fine. My ex has got her neice, her grand-daughter and her boyfriend / nephew, and we share them all , so I have got plenty of other wee darlings to keep me busy.
They are worth it.
