If your daughter gave her blessing i think you have done the right thing, though being overly sentimental and a bit of a hoarder myself know how hard that is. I may have put a couple of small things aside. ....
I am sorry your grandchildren are so far away. It must be hard though at least we now have facetime etc so it is easier to keep in better touch, but yes, i am sure you, like most of us perhaos, woukd prefer them to be closer but our children have the world to choose from and many choose to move away, as my daughter did too 10 years ago now.
I am sure the rotary will find good homes for the toys and your loft will be clearer.
