Here's a video of Jeremiah and me playing in the sand. He's scooping sand into a plastic container. At one point someone walked behind Daniel, and Jeremiah waved at him, trying to get his attention. Alas, the person didn't notice.
And here is a video of Jeremiah learning to roll "dice." When Daniel and I were playing Yahtzee, Jeremiah was intrigued with the dice, so I found a large plastic cup and put some plastic letters inside.
