Yo yo yo! Check out my book

Above is a digital version of the Computer Engineering for Babies. Use the arrow keys or click/tap the edges of the book to turn the pages. You can also click the buttons. For the AND and XOR pages, you can click to unpress the buttons to see how the various components work. (If you're using a touch device, then you can use multiple touches to press buttons at the same time).

I have been working on a physical board-book version, off and on, for a couple of years, and now I am serious about starting the first production run in the next few months. It will have large working buttons and an LED and be an awesome intro to digital logic for literally every age.
