As I type this, Jonathan is picking up his blocks for bedtime, jumping from place to place rather than walking. He looks as though he's practicing for the long jump each time. He falls down every other jump or so, and just says, "Whoa..." and gets back up and jumps again. He throws his arms back in classic superhero fashion before dashing between rooms to look for more blocks and pauses for a drink of water when he needs it. The actual pick up time is probably tripled by all of this, but I don't really mind. All I can think is that he's not a toddler anymore. At 3 1/2, he's really a little boy.
Almost as soon as I hit publish, Jonathan took to spinning while jumping, with poor result. He fell and scuffed his nose. As I said, really a little boy.
