I am loving Nathan's newfound sense of altruism. We brought him to my parents' cabin in NH for a few days over the holiday weekend - he brought a box of cereal in from the car all by himself. Today he brought in a package of toilet paper as I was unloading groceries. Usually I have to leave the groceries and take him in by himself, so this saves me quite a bit of effort.
Mike has even taught him to follow basic commands. Like today, Mike pointed at the cup of ice water he'd accidentally left across the room. With a little prodding, Nathan actually picked it up and brought it to him- without even spilling any, bonus! He can also be told to clean things off the floor and place them in the trash.
This is why we had kids, right? To make them do our bidding?
