The biggest thing would be, like AngMc, wanting to take them on a trip to the Czech Republic. Like perhaps most older moms, if I could live to hold a grandchild in my arms, I would be the happiest woman in the world -- hoping that doesn't invite "Bedazzled"-type scenarios of one of my sons impregnating a girl at 14 or something.
The main things I'm looking forward to are taking the boys to baseball games with their dad, playing mini-golf (what's the youngest it's practical to do that?), going to water parks, watching them play catch with DH and learn how to work on cars. Their dad really likes astronomy, so maybe we could take them out to the country for stargazing.
