A new little activity E and I have taken up is walking to the end of the street and back (ideally without crying). E pushes the push toy and says, "uh-oh" anytime he sees it's about the veer off the sidewalk. Sometimes he takes a few steps up a neighbor's sidewalk. He likes it when there's something extra going on in the neighborhood, like a tree getting cut down, the moon shining or a rock to hold in his mouth. It's the little things. But honestly this 20-30 minute activity is just the ticket.
