I’ve been deliberately cultivating his long attention span. Whatever he’s interested in, that’s the most important thing, so I encourage him to keep doing that as long as possible. I never say, “Come on! Let’s go. We’ll go to the beach or forest, and make things with sticks for five hours before he’s ready to switch. Other families come to the playground for 20 or 30 minutes, but we’d just stay there for hours, immersed in some newly invented game. Nobody else can hang with us like this. Everyone else gets so bored. Of course my adult mind wanders to all the other things we could be doing. But I let it go, and return to that present focus.
