Your son sounds very similar to my son so it’s nice to see others that get it. I feel like people wonder why I do any curriculum at all but honestly it’s usually his idea! We’ve been dabbling since 3.5 years old. He’s 5 1/2 now and going into “kindergarten” this coming school year. My other son though is almost 4 and not quite ready yet. It’s funny how different they can be. ❤
