Also, the other day I noticed a bunch of cereal crumbs mashed in a little crevice in one of our kitchen chairs. It was a skinny spot, so I grabbed a little 3x5 card and scraped it along there -- hoping to flip the crumbs out. A few minutes later I returned to the kitchen to find Jesse just finishing up the same activity with the card and the chair and loudly proclaiming, "I did it, Mom!"
"What did you do?" I asked.
He looked at the card; down at the chair; then replied, "I don't know." I loved that he was just mimicking what he'd seen me do even though he had no idea why anyone would do it or what it would accomplish.
