First, he made a "drawing book". He drew a bunch of pictures on paper, stapled them together and plans to take it home to give to S2 so that she can color them.
Next, he did a 100-piece Spiderman jigsaw puzzle. This occupied him for more than an hour.
Then, he commandeered a couple of packing boxes that have been lying around in my office for several months. I was wondering what he was doing with them. It turns out to be a train. He is sitting in the first car, reading a book. All his other stuff is in the second car.
So, he's managed to occupy himself for 6 hours now. I can't imagine S2 being so patient and self-directed. Difference between first and second children?
