TJ needed to be held all night, but he was definitely perking up this morning (as the doctor predicted). Nonetheless, this was his reaction to the National Zoo and Aquarium today (we had a babysitter standing by at home, and after two hours my Mum dropped him off): 
Later, however, he saw what Dad had done with one of the balloons now infesting our home (Louisette likes balloons; today is her 3rd birthday). That was cool. (An interesting contrast to Louisette, who often objects to things not behaving as they should, and asked us to remove the balloon.)
