There aren't a lot of "activities" available to the under-2.5 crowd these days, so we take what we can get.
Mine was easy peasy to make. I happened to have a cake tin collecting dust with my other (not disposable, but also collecting dust) cake tins. I poured into it rice (it was on sale in the bulk aisle of Whole Foods) and Black Beans (ditto the rice) and sticky gummy frogs (party favor bag aisle at Target) and tiny pom poms (ditto the frogs.)
Baz dove in.
He dug around.
He made a mess.
It's not fun if it's not messy.
Dad "helped," too.
And then, for the coup de grace, I gave him a "scoop."
Good times, my friends. Good times.
