We had heard of the “why” stage and naively thought we might skip it because we were so good at explaining things to Cooper. Joke was on us. As Rob put it, “Cooper has adapted “5 whys” for his own use. I call it “500 whys”.” This has been an incredibly eye opening stage of development making us really thing about exactly “why” something is the way it is. The increase in asking “why” wasn’t gradual, it just exploded today and is holding steady in frequency.
