Maybe ask the grandkids what they want, or a wish list from them.

My favourite presents I remember as a kid:

1. A tiny toy grand piano with black keys that WORKED, and a wee music book to figure out some simple tunes. I nailed Twinkle Twinkle Little Star before breakfast Christmas morning. I was 5!

2. A MICROSCOPE!

3. A CHEMISTRY SET! I followed some of the directions...then experimented on my own. I was - 8? I created a neat blue liquid, then added something and it turned a brilliant green! Mom and Dad never had a son, but I caused Mom enough worry about blowing up the house to make up for it!

Listen to them - to what they love.
