That’s awesome! I’m not familiar with that book, but I’m sure it doesn’t hurt. About to start… so 5-ish years old. I recommend books by Nick Selk, also known as The Awkward Yeti. He makes comics, like Heart and Brain, about the body and other science topics. The Sun Is A Big Deal, The Brain Is A Big Deal, and Onward To Good Things are three child friendly ones. I adore his comics too.
