You gave me a good laugh, @Julia! If there were a Grandmothers Club, that's where I would belong! My kids are in their late thirties. I do, however, have 2 little grandchildren who love to dance and play percussion. Unfortunately, they don't live close to me, but the last time we saw them, their parents invited some friends over for a jam (I got to play cajon) and the little ones happily participated. The then-4-month-old sat on my lap and "helped" me play percussion with an interesting wooden percussion instrument that I brought them as a present from Russia.
